We inquired as to the effect on the operatives of this animalized atmosphere, and were informed that it was not known to be injurious. On the contrary, it was stated as a singular fact, in connection with the late visitation of cholera in Aberdeen, that not a single comb-maker had been affected by the disease, at least fatally; whence it may be inferred, although we do not pretend to assign the reason, that the fabrication of horn must be attended with considerable anti-miasmatic effects. At all events it is certain that horn-dust cannot exercise that injurious action on the air-passages and the lungs which is experienced in many trades, such as that of the steel-grinders of Sheffield.

Passing over one or two intermediate stages after the combs are thus cut and twinned—such as "thinning" on the outer edge by means of grindstones, and "pointing," by means of peculiarly-shaped bevel-saws—we arrive at the next department, where the finishing is given by the hand. Here we meet with artificers who, with a pertinacious reverence for ancient usages, preserve among themselves the appellation of comb-makers par excellence, forgetting that the very boys and girls in their respective departments play as important a part in the aggregate production. And yet, in their province, they are deserving of commendation. The specimens of elaborate and skilful decoration displayed here, especially on ladies' braid-combs, were admirable, and one pattern was shown us wherein there was a species of chain, formed of beautifully stained horn, woven with the head of the comb, which, although we examined it minutely, and knew there must have been a joint in each alternate link, we nevertheless failed to discover. It is in this department that the teeth are smoothed and rounded—an operation technically termed "grailling"—which is effected by different sorts of cutting rasps. So far as the making or formation is concerned, the combs are now finished.

At the opposite side of the buildings we were taken to the department where the staining is carried on. This will be better understood if described as the imitation on the various classes of combs of the natural diversity of tint in tortoise-shell. The horn, whether in plates, as in the side-combs, or after being "twinned," as in dressing-combs, is immersed in diluted nitric acid, which, with its characteristic action on all organized tissues, creates a deep and permanent yellow stain. This resembles the ground color of tortoise-shell; and to produce the variegation, the horns are then treated with a particular composition of red oxide of lead, with certain alkaline compounds, which has the effect of neutralizing the action of the acid, and imprinting a stain of a deep orange color. After being carefully washed, dried, and polished, the surface of the combs presents the beautiful and natural appearance desired. Indeed, the imitation is so perfect in the best classes of stained combs, that a practised observer can only detect it. We were shown, for example, two specimens of braid-combs, one of real tortoise-shell and another of stained horn; and so much alike were they in color and configuration, that we could not tell which was which, and yet the one comb was worth about ten times as much as the other. This operation of staining, which is somewhat artistic, is performed by women.

There are still some minor departments, which we need not describe in detail. "Buffing" consists in smoothing the rough surfaces of the horn by means of wheels covered with walrus skin. Side-combs and braids are bent to their peculiar curve by being first heated and then fastened to wooden blocks—an operation that lasts only a few minutes. Pocket-combs have of course a different and peculiar treatment in some stages; such as the formation of the joint, and the putting together of the handles. And there is a department exclusively devoted to the fabrication of horn-spoons, which becomes chiefly remarkable from the circumstance of there being no modern application of machinery to the manufacture. The last process, however, to which all combs are subjected, is that of polishing, which is effected by wheels, covered with leather of different degrees of softness. After this they are despatched to the warehouse, to be assorted the last time—the side-combs being stitched to cards, or packed in fancy boxes, which affords constant work to about twenty women.

We were finally shown the patterns of the different kinds of combs, many of them exceedingly beautiful; but we can only notice them in regard to number. Of dressing-combs (counting the different sizes of all the patterns), there were 605; ladies' braid-combs, 612; ladies' side-combs, 525; pocket, small-tooth, horse combs, and sundry articles, 186: in all, 1928 different varieties.

The aggregate number produced of all these different sorts averages upwards of 1200 gross weekly, or about 9,000,000 annually. The annual consumption of ox-horns is about 730,000, being considerably more than half the imports of 1850; the consumption of hoofs amounts to 4,000,000; the consumption of tortoise-shell and buffalo-horn, although not so large, is correspondingly valuable: even the waste, composed of horn-shavings and parings of hoof, which, from its nitrogenized composition, becomes valuable in the manufacture of prussiate of potash, amounts to 350 tons in the year; the broken combs in the various stages of manufacture average 50 or 60 gross in a week; and as the crowning illustration of the enormous extent of these comb-works, the very paper for packing costs L.600 a year.

There are so many beautiful instances of the division of labor that the task of selecting is not easy. But let us take the cheapest article in the trade; namely, the side-combs, sold retail at 1d. per pair: in its progress from the hoof to the comb—finished, carded, and labelled "German shell"—it undergoes eleven distinct operations. This comb, which twenty years ago was sold to the trade at 3s. 6d. per dozen, can now be purchased in the same way for two shillings and sixpence per gross! thus effecting a reduction in price of about 1600 per cent. As an illustration of the value of labor, we give the following comparative estimate of the produce of the three materials:——

1 cwt. shell,val.L.200,producescombs,val.275,inc.37-1/2per cent.
1 ton horns,"56,"""150,"168""
1 ton hoofs,"12,"""36,"200""

Regarded in this aspect, in the relation of labor to material, we find that hoofs—intrinsically the least valuable of the materials—become, with the application of labor, the most valuable—that is, proportionably: and the converse is true in the case of tortoise-shell.

At the time of our visit there were employed 456 men and boys, and 164 women—in all, 620 persons—exactly four times the number employed in the comb-trade in all Scotland when the house commenced business.
