Dalbeattie Granite Industry
History and description of Messrs D H & J Newall's Works.
By Ivie A Callan, Editor, "Stewartry Observer"
THE prosperity of Dalbeattie depends on the granite trade, upon the
condition of which the population rises or falls. The last census showed a
considerable increase, and indexed also renewed activity in the staple industry
of the Granite Burgh. Before proceeding with the history of the firm of Messrs
D. H. & J. Newall, and a description of their works, it might be well to ask
such questions as - What is granite? What is its origin, its composition, its
age?
Granite is a rock about which there was, and is, much apprehension; and
perhaps the most common of all mistakes is in regarding it as the oldest of all
rocks, forming a foundation for all others. This is not strictly correct, as
granites are known to be of widely different ages - some very old, some
comparatively recent, and some to have risen through stratified rocks of every
period of time, just as Dalbeattie granite rises through the adjoining
whinstones, disturbing and sending veins into them, thus clearly proving that
granite is the intruder, and consequently the more recent. Granite is classified
as belonging to the order of igneous rocks - i.e., rocks which have resulted
from a molten condition, cooling from a state of fusion - not on the surface,
however, like the lava of a volcano, but at greater depths below the surface,
and at enormous pressure. None of the features of the lava mark the granite,
which is always completely crystalline in texture, homogeneous-like in its
arrangement of its mineral constituents, presenting quite a contrast to the
heterogeneous-like aspect of the lava.
If we were to cut down any active volcano some thousands of feet below the
surface, we would probably find granite. In our country we have had volcanoes
cut down by the never-ceasing action of wasting influences, the islands of Skye
and Mull being good examples. Dalbeattie granite has doubtless had the same
origin, but at a very much earlier period in the world's history. Every trace of
the lavas and other associated igneous products have long since been swept away,
leaving nothing but the ancient cores or shafts of granite rising through the
slates of the Silurian age, so that what is now exposed to the surface was at
one time far below it. Granite is composed of; among other minerals - quartz,
felspar, mica, and sometimes hornblende schori; the chemical parts being -
silica, alumina, iron, lime, magnesia, etc.
INAUGURATION OF THE INDUSTRY.
It is not with any degree of accuracy that the actual date of the
commencement of the granite industry can be stated, for it gradually grew from
the gathering of boulders in the district. It is not thought that there were
quarries in Dalbeattie one hundred years ago, yet the centenary of Buittle
bridge took place in 1897, the stones for which were brought from a distance,
although Craignair was close at hand The earliest recorded date of business done
was in 1821, when the grandfather of the present Laird of Munches gave a
certificate order for a pair of granite gateposts; while it is also recorded
that on March 17th, 1828, Mr Andrew Newall paid the proprietor for 26.5 tons of
granite at one shilling per ton. This, it is presumed, was gathered up mostly
anywhere on the estate. "Auld Andrew" Newall, great-grandfather of the
present generation - began quarrying first at Craigmath, Barrhill, Old Land,
Newabbey, and latterly at Craignair; and the business has remained in the family
ever since, the firm still trading as Messrs D. H. & J. Newall, although
none of these men are now living.
A VISIT TO CRAIGNAIR.
To have some idea of how the jagged rock is dislodged and cut, in your
imagination accompany us to the quarry. See yonder men on the niche on the
perpendicular face of Craignair. Busily they are boring far into the rocky hill,
making holes oft-times thirty feet deep ere the charge of powder is rammed in.
Listen to the tremendous crash of the explosion, which may be heard for miles
around, followed by a great rush of granite boulders, causing a noise like unto
an artillery duel. Picture, later on, the floor of the quarry strewed with
immense heaps of rocks, including blocks of granite weighing hundreds of tons.
(A few years ago, along with Mr H. Gillespie, we measured a stone as large as
many a cottage, and which weighed nearly 700 tons). Lying in the rough in the
quarry, the blocks which are intended for the hands of the hewers are marked off
by the foreman where they are to be cut. The driller is next called into
requisition, and on the lines marked for him he drills a number of holes
(dependent on the size of the stone) about six inches apart, and about three
inches deep. Into these small plugs are driven between two thin pieces of steel,
causing the plugs to act as wedges. These plugs and feathers, as they are
technically termed, are driven, one after the other, into the stone, the
operator endeavouring to make them all have the same strain, the stone being
thereby split in two, and in this state taken to the mills. When a stone is
placed on the "banker" the hewer is given a sketch of what is wanted,
and if the stone is too large for the purpose intended, he knocks off the
superfluous rock with a mash hammer. He proceeds to lay his lines for squaring
the face by hewing a little piece off at each corner, and on this he places two
little squares and tries it up with a straight edge. Having got the lines
correctly he then proceeds, with a punch, to get the rough off, and when this is
done a single axe is brought into play, and the whole face axed down to a
uniform level. If the work is to be unpolished, the patent axe or bush hammer is
next applied. In all work where there are mouldings, the workmen are supplied
with zinc models showing the various members, and from these models he has the
reverses made in thin wood, which he can apply to his work and so determine if
his curves and squares are true.
In some cases full-sized drawings of work are made on the boards, and from
these drawings the workman can get all his details. In carved work, models in
Plaster of Paris or Caen stone are usually furnished, although carving or
incised work may be done from drawings.
IN THE POLISHING MILLS.
The first attempt to polish granite was made in 1834, the stone, a small
piece of granite, being now in the possession of Mrs James Newall, Liverpool,
whose grandfather polished the stone on a freestone flag. In 1841 a memorial
stone was polished in a shed at Craignair. The method was crude, and it was
considered an impossibility that a polished surface could be put on a granite
block. Perseverance and emery, however, proved the practicability, although. the
men almost despaired of accomplishing the task, for, after a certain finish had
been obtained, the more they rubbed the worse it got, the coarse emery, when
renewed, scratching the stone badly. The polishing was all done by hand, with a
plane-shaped box hollowed in the plain surface. A wood frame is placed round
them a little lower than the edge of the stone and then covered in with plaster
of Paris, to prevent the iron rings which are used in polishing from breaking
the edges of the stone. These vertical machines, as the name indicates, are
upright shafts, having at the lower end a ball on universal joints, to which a
series of iron rings, or in some cases only one ring, are attached. The upper
end of the shaft is also on universal joints, and moves in a loose socket, with
a back-weight attached to regulate the pressure of the rings on the stone. The
ordinary vertical, although still largely used, has lately been superseded by
the radial polishing machine - a larger machine with much heavier rings, worked
by a central upright shaft, and swung from place to place on the stone by a
pivot arrangement at the side. Messrs Newall have a machine of even newer
construction, which, being worked on a large central pivot pillar, can be swung
round and set to work on one carriage while the stones in a carriage on the
opposite side are being got ready. The man in attendance sets the machine in
motion, and begins the polishing process by throwing into the rings a mixture of
diamond grit or chilled iron (globular in form and something like very fine
shot) and water; the rings in their revolutions being guided over the surface by
the attendant. Four or five hours' running with this will have rendered the
stone wonderfully smooth. The whole stuff is then washed off, the utmost care
being taken that no particle of the grit remains to damage or scratch the
surface in the next process. After washing, the plaster, where broken, is
renewed; :he rings replaced, and the same process gone through, this time with
carborundum* and water. This process is continued until the granite is
absolutely smooth, and the carborundum ground down to a fine paste.
Carborundum is a very fine powder, something like emery, but cleaner,
sharper, and brighter in appearance It is made from corundum, rock and sand
being mixed together and passed through a furnace under enormous heat. The
melted product, after cooling, assumes all the tints of the rainbow. It is
ground into powder, and imported in this form for polishing purposes, and has
almost superseded emery in the second process of polishing granite. It is
manufactured at the Falls of Niagara.
The washing process is then repeated. The next operation is the final one in
polishing, and is accomplished by means of "putty powder" (oxide of
tin) and felt, the latter being fixed on the iron rings. This gives the gloss to
the stone, and finishes the polishing. All moulded stones are polished in what
are known, from their motion, as pendulums. Plaster of Paris casts are taken of
the moulding, and reverses of these are procured in cast iron to fit the stone.
The polishing process is then gone through on the same lines as that previously
described.
GRANITE SAWS AND TURNING LATHES.
Within recent years Messrs D. H. & J. Newall have brought saws into use
with good effect. These saws also have the pendulum motion. A steel blade, or
blades, with the aid of diamond grit - a coarser quality than that used for
polishing - and water, cuts the block, thus giving two clean faces without the
aid of hewing. If the blocks are to have fine-axed faces it may be necessary to
go over them lightly with a patent axe; but if for polishing, they can go right
from the saw into the polishing machines. Circular work is now nearly all done
by turning lathes, with a circular cutter working at an angle on both sides of
the stone. Boring is also done by machinery, and holes through paint rollers,
etc., are bored with the aid of a hollow steel tube attached to a vertical
revolving shaft. This machine is also fed with diamond grit, and the core which
is left in the inside of the drilling can be converted into small columns,
whereas, in the old method of dressing by hand, the whole centre was, of course,
bored out.
THE CRUSHING MILLS.
Stones for the mills, those used for architectural and monumental purposes,
must necessarily be of fairly large dimensions. Smaller stone is used for making
setts, and the chips are crushed for granolithic purposes. With Dalbeattie lies
the honour of first introducing as a business the crushing of granite for
granolithic paving. Like all other branches of the granite industry, it had a
small beginning. Messrs Shearer, Smith, & Co. were the first to erect a
crusher, but previous to that they had men employed riddling the sett-makers'
chips, for which the price was then fifteen shillings per ton.
Messrs D. H. & J. Newall were among the first to erect a crusher, but
the demand for crushed granite, for granolithic and, Macadam purposes,
increasing so greatly, in 1898 the firm erected a machine which is capable of
turning out 300 tons per day, in sizes from three inch Macadam to the smallest
size of crushed granite used for concreting purposes. One of the incentives for
its erection was the advantageous disposal of the ever-increasing mountain of
refuse granite which was accumulating on the banks of the River Urr. The huge
"tip" was calculated to contain nearly one million tons of granite,
and at one time was considered unprofitable and was a source of concern to the
management of the quarries; but the words of a gentleman, uttered twenty-five
years ago in Dalbeattie Town Hall - "that these huge mounds of granite
would by-and-bye disappear, and be utilised in the formation of the streets of
London and the other large towns throughout the kingdom," although at the
time considered to be rather overdrawn, have proved to be truly prophetical, and
are now being realised.
The ground occupied by the is eighty-six feet long by fifty-one feet wide.
The roof of the screening room is fifty-eight feet high. We will try to give
some idea of "crushing" in operation The stone is hauled from the
quarry " tips" and dumped into the two hoppers, where the crushing is
done between a cone placed on a gyratory vertical shaft through the centre of a
cylindrical shaft. As it gyrates the crushing cone impinges against the side of
the shell, in relation to which it is constantly approaching and receding.
Passing through these breakers, the crushed granite is caught by a set of
elevators and taken to the screens, measuring forty inches in diameter, and
sixteen feet and twelve feet long respectively. The screen for No. produces any
sizes from 1.25 in. to 3 in., and can be changed at the shortest notice. The
rejections of this screen fall down a shoot into No. 3, where they mingle with
the smaller material fed into this crusher. The produce of No. crusher is taken
up by a second set of elevators to the screening room, where it passes through a
screen with a inch, 0.375 inch, or 0.5 inch diameter mesh, or whatever size may
be wanted. The rejections from this screen are made to pass through another
shoot to a set of rolls with an ingeniously contrived rocking arrangement on the
top, so as to distribute the granite equally over the surface, and from these
rolls it is again elevated to a small mesh screen, through which it has now no
difficulty in passing. No. crusher is capable of producing 200 tons Macadam, and
No. 3, 100 tons crushed granite daily, making a total of 300 tons. Below the
screening room there are six large bins, supported on high walls of solid
concrete, capable of containing 50 tons each.
THE ENGINE-ROOM.
The engine-room is a model of neatness, and is fitted with glazed bricks.
The engine is a self-contained throttling one, and is designed for quick motion,
and may be run at almost any speed. A Worthington boiler feed-pump of the piston
pattern, and which is good for 150 lbs. pressure, is in close proximity to the
engine. The boiler is a horizontal tubular one. Its horse-power is based on 30
lbs. of water per hour, which the pump supplies with ease. Water is obtained
from a well sunk in the room. The engine-room is fitted with electric bells
communicating with the crusher platform and the screening-room above, so that in
case of accident, or for any other cause, the whole of the machinery can be
stopped immediately at a signal from either of these places.
THE AERIAL ROPEWAY.
When it is known that Messrs Newall turn out 25,000 tons of crushed granite
annually, it will be readily recognised that the question of transit would prove
a difficulty when undertaken by carting. Under such circumstances traffic was at
times bound to become congested. To obviate the difficulty the managers (Mr W.
N. Newall and Mr Gillespie) considered what system was most to be preferred. At
first it was intended to construct a railway track, but the difficulty of
bridging the River Urr had to be contended with, and ultimately the idea was
abandoned as being much too costly. Mr Newall and Mr Gillespie then visited
several ropeways running in the South of England, and came to the conclusion
that a ropeway between Craignair and the railway was the thing required, and was
forthwith erected. An idea of the saving of labour effected may be gathered from
the fact that after the granite chips are thrown into the crusher, the produce
is not again handled.
The crushed granite is conveyed to a special railway siding, constructed
near Meikle Dalbeattie, by means of buckets drawn by a wire rope running round
pulleys at each end. The buckets travel under the crusher bins (already
mentioned), where six of them can be loaded at once, by simply pulling a lever.
They are then pushed from under the bins and automatically leave the rail at the
terminal station and are taken on by the cable. When once on the rope the
buckets can only be released by lifting them bodily off, but if by chance or
carelessness a load is allowed to run along to the station shunt rails
unattended it would simply take on to the cable and automatically fix itself.
The distance between the two stations is 870 yards, and to support the cable
there are six graceful Eiffel-tower-like steel trestles from 30 feet to 50 feet
high. Twenty-two buckets run on the cable, each having a carrying capacity of
six cwts., and are calculated to convey 200 tons in a day. Along the extreme top
of the trestles is a telephone wire connecting the two terminal stations. In the
crusher buildings a six horse-power vertical engine drives the ropeway. Railway
waggons are run alongside the station terminal and filled direct from the
buckets, which are tilted by the man in charge. The waggons then pass over a
weighing-machine specially constructed for the purpose. The ropeway is the first
of the kind erected in Scotland.
SETT-MAKING.
Another important branch in which granite is employed is the laying of
roadways, tramways etc., with setts. It is important in
more ways than one, if only from the fact that the "causey-men," or
settmakers, are the highest paid of granite workers. The fact is not due to any
extraordinary skill or intelligence being necessary, but is alone attributable
to the advantages pertaining to a well-conducted union. This the men have long
ago recognised, and today have a larger percentage of workmen affiliated than
any other workers' union in the country. We cannot ascertain when granite setts
were first used, but it is many years ago. Of late years an attempt has been
made to introduce wood paying, and in many places it has superseded granite, but
where a hard-wearing, non-slippery surface is required recourse has to be made
to granite, and in this respect Dalbeattie granite excels all others. It is many
years before Dalbeattie granite is worn smooth, which is accounted for by the
fact that the concussion caused by the horses' shoes, instead of acting as a
polisher, in reality roughens the stone. Should you take the trouble, when in a
city whose streets are paved with Dalbeattie granite, to examine a sett after
being struck by a horse-shoe you will see what we mean. Although the first
outlay is more than whinstone or some wood pavements, it is cheaper in the end,
as the following table of the relative cost of wood and Dalbeattie granite, with
the expense of maintaining each for thirty years, will show.
OTHER QUARRIES.
Owing to the high face of Craignair Quarry it is often very difficult to
obtain stones large enough to suit the firm's requirements, and to other three
new quarries have been opened up, two in the RounaIl Wood and the other in the
"Coo" Park. The former were opened last year, and some splendid large
blocks obtained therefrom; but the one in the Coo Park, which was opened this
year, promises to exceed in quantity and quality anything in the neighbourhood.
At these quarries steam boring machines are in use, and effect a great saving
not only in labour but also in the time taken to dislodge the granite.
PETERHEAD AND WESTERLY QUARRIES.
In the yard there can often be seen the fronts of some buildings in red
granite. The blocks are obtained from the firm's quarry at Peterhead and brought
to Dalbeattie in a rough state. Here they are polished or carved as they may be
required, and as in the case of all other work, carefully built and fitted in
sections previous to being despatched. Here may also frequently be seen the
close-textured grey granite from their quarries in Westerly, Rhode Island.
THE MANAGEMENT.
After the death of the two senior partners, Mr Homer and Mr David Newall,
the business was carried on by Mr Joseph Newall, in whose hands the works
assumed large dimensions - and were placed on a sounder commercial footing.
Mr Newall, who was a man of wide scholarly attainments and of a particularly
sociable disposition, was greatly respected and beloved by all who came in
personal contact with him, and his death was a great blow to the district. The
business was left entirely in the hands of his widow, who shows many of the
characteristics of her late husband. In all of the many improvements undertaken
within recent years Mrs Newall has displayed a keen interest, and her counsel in
the affairs of the firm has proved of marked value. This article would be
incomplete, however, were we to omit any reference to the two gentlemen on whom
fall the direct responsibility of the management - Mr H. Gillespie and Mr W. N.
Newall. The management forms a happy combination of long and tried experience
and youthful enthusiasm and up-to-dateness. Mr Gillespie has been connected with
the firm nearly all his life, and has seen it grow from a small concern until
now it has taken its rank among the leading granite firms of the country, and to
him in no small measure is its present position attributable. Mr W. N. Newall is
a direct descendant of the founders, and the recent additions and improvements
to the plant may be traced to the knowledge he acquired during his visits to
America. Nor is his knowledge of the " arm-chair order, for he makes
himself conversant with the minutest details by personal supervision. Under such
a managerial combination progress and success are assured.
In drawing this article to a close, we may be permitted using the words of
Mr Gillespie when he said it was only natural, when we think of the works of
architectural beauty and the skilfully executed sculpture work of our granite
craftsmen, that we should be proud of our native granite. Craignair will never
be allowed to fade from our memory. Even should it do so for a time, some
building or monument will meet our gaze to awaken and refresh us. The Great and
Little Bass Lighthouses (Ceylon) shed their beacon lights over the Indian Ocean,
and furious cyclones beat against their solid structures of Dalbeattie granite.
The billows of the Atlantic hurl themselves against the base of the Eddystone
Lighthouse, and there the same material bids defiance to their almost resistless
charge. Stately ships sail in and out of the harbour of Trinidad, the old
Stanley Dock in Liverpool, and numerous docks and harbours throughout the United
Kingdom, and find safe refuge therein, sheltered by the solid masonry from the
same old hill.
The rock from its bosom has taken its place, among others, in
beautifying the Thames Embankment. Its polished brightness embellishes the
frontage of many a bank and office and public building; and endless traffic is
carried on, and millions of people pass daily over, the hardy, material
abstracted from her sides to form the highways and cover , the pavements of
numberless cities and towns throughout these realms. In contrast with the
stirring and stormy use for which our native granite is adapted and adopted,
many beautiful memorials, selected from the same prolific source, have been
reared throughout this and other lands. It has been used to commemorate the
virtues and bravery of not a few of the nation's heroes, amongst them Lord
Nelson, General Gordon, and General Neill. Dukes, earls, and statesmen have
chosen it to form their last resting-place, and the lovers of Shakespeare and
our own beloved Burns have not been behind in acknowledging its beauty and its
worth. Travellers will find it in America, in Africa, in China, in Australia,
and in many parts of the European. continent; and even from the little town of
Tiberias it stands proudly overlooking the blue waves which nightly roll o'er
deep Galilee. Truly, then, we may well unite in singing the praises of this
grand old hill in the words of the poet Sproat:
Then let us join at Nature's shrine
And breathe our earnest prayer;
That though she gave no golden mine
She blessed us with Craignair.
