The gauging of casks, which is performed by a large staff of, generally speaking, skilful and highly meritorious officers, is quite a science in itself, and requires years of constant practice to make the operator thoroughly proficient. But in this, as in other arts, there are of course various degrees of excellence. In the Customs service—and the same thing will doubtless apply to the Excise—there are gaugers who stand head and shoulders above their fellows, and who appear to have the power by merely glancing at a cask, as if by intuition, to tell its ‘content,’ as its holding capacity is officially styled. Although it has been the usage in certain quarters to speak in contemptuous terms of the functions of this deserving class of public servants, and to apply to them the opprobrious epithet of ‘dip-sticks,’ we have no sympathy with such detraction, which is quite unmerited.

It would be impossible within the brief limits of this paper to describe minutely the various operations in bond which are daily going on at these stations. Such comprise Vatting, Blending, Mixing, Racking, Reducing, Fortifying, Bottling, Filtering, &c., and would in themselves suffice for a separate article.

Having given a very meagre outline of the multifarious duties and processes carried on at the various bonding vaults in London and elsewhere, we may perhaps fitly conclude with a brief description of certain antiquarian features of special interest, to be met with in Messrs B——’s premises. As previously remarked, the monastic character of one of the leading approaches is conveyed in the title of Crutched Friars. But it is evident from other and various remains that its site includes a most important portion of ancient Londinum. A considerable extent of the old Roman wall, upwards of a hundred feet, in an excellent state of preservation, ‘the squared stones and bonding tiles’ being marvellously well defined, forms the boundary of what is known as the ‘South’ Vault. On a higher level, styled the Vat Floor, in the medieval portion of the City wall, is to be seen a fine specimen of the Roman casement, which is said to be the only one now remaining in the City. According to the best antiquarian authorities, these remains form a part of the circumvallation of London begun in the reign of Constantine and completed by Theodosius. As is only natural, these relics are highly prized by the Antiquarian Society, which has in no ordinary terms expressed its appreciation of the zealous care bestowed by the proprietors in preserving these unique and priceless treasures of the past.


THE MONTH:
SCIENCE AND ARTS.

Professor Janssen, the well-known astronomer of Meudon Observatory, who has done more than any man living, perhaps, towards wedding the photographic camera with the telescope, has lately published some account of a marvellous picture which he obtained of ‘the old moon in the new moon’s arms.’ At the time that the picture was taken, the moon was only three days old, and an uncovering of the lens for one minute only was sufficient to secure the image. This image is feeble, but is full of detail, plainly showing the general configuration of the lunar surface. Professor Janssen believes that this application of photography points to a means of obtaining more precise measurements of the light, and of studying the phenomena which are produced by the double reflection of the solar light between our earth and its satellite. To the uninitiated, in these days of marvellous instantaneous pictures, an exposure of one minute may seem rather a long period. But let us consider for a moment what a very small proportion of the sun’s glory is reflected to us from the moon, even on the finest nights. Professor Sir W. Thomson gives some interesting information on this point. Comparing the full moon to a standard candle, he tells us that the light it affords is equal to that given by such a candle at a distance of seven feet and a half. As in the above-mentioned photograph the light dealt with came from a moon not full, but only three days old, it will be seen that Professor Janssen had a very small amount of illumination for his picture, and the only wonder is that he was able to obtain any result at all.

It will be remembered that in the autumn of 1882, a series of observations were commenced in the polar regions, which had been organised by an International Polar Committee. Fourteen expeditions from various countries took up positions in that inhospitable area, with the intention of carrying out observations for twelve months, from which it was hoped that valuable knowledge would be gained. This programme has been successfully carried out, ten of the expeditions having returned home, many of them laden with rich stores of observations. Three remain to continue their work for another year. As to the return of the remaining band of observers—belonging to the United States—there is as yet no definite information.

On Ailsa Craig, Firth of Clyde, there is being erected, by order of the Commissioners of Northern Lights, a mineral-oil gas-work, to supply gas for the lighthouse in course of construction there, as well as to feed the gas-engines which will be used to drive the fog-signalling apparatus. The works are being erected by the patentee of this gas-system, Mr James Keith, and will cost three thousand pounds. They will be capable of manufacturing two thousand cubic feet of oil-gas per hour, of fifty-candle illuminating standard. It has long been the opinion of many that the electric light is not the best illuminant for lighthouse purposes, and this installation at Ailsa Craig, following one on the same principle at the Isle of Man not long ago, would seem to indicate that the authorities think so too.

North-east of Afghanistan there lies a piece of country called Kafiristan, which, until April last, had never been traversed by the foot of a European. In that month, however, Mr W. W. M‘Nair, of the Indian medical service, crossed the British frontier, and travelled through the little-known region for two months. An interesting account of his wanderings formed the subject of a paper read by him at a recent meeting of the Royal Geographical Society. The country is inhabited by three main tribes—Ramgals, Vaigals, and Bashgals, answering to the three chief valleys, and each having a distinctive dialect. The men are warlike and brave, but, like many other semi-barbarous peoples, leave the heavy work of agriculture to the women. The Mohammedans hem them in on all sides; but as the tribes are at peace among themselves, they are able to hold their own. Slavery exists to some extent. The people acknowledge one supreme being, Imbra, and worship at temples presided over by priests; but to neither priests nor idols is excessive reverence paid. Bows and arrows form their chief arms; and although a few matchlocks have found their way into the country from Cabul, no attempt has been made to imitate them. Wealth is reckoned by heads of cattle; the staple food is wheat; and the favourite drink pure grape-juice, not rendered intoxicating by fermentation or distillation.

Although there is every reason to believe that cruelty to animals is far less common than it was, still there are many men who are not so merciful to their beasts as they might be. Many of these offend from ignorance, and will leave poor creatures exposed to inclement weather under the belief that they will not suffer. Professor Shelton, of the Kansas State Agricultural College, has lately shown, by careful experiment, that it pays to be merciful in the matter of providing shelter for pigs; and we have no doubt that if his researches had been extended to other animals, a similar result would have been obtained. For this experiment, ten pigs, as nearly as possible alike with regard to breed, age, &c., were chosen, five being kept in a barn, and five in the open, but provided with straw to lie upon. These two families were fed twice a day with carefully weighed messes of Indian corn. In the sequel, it was found that each bushel of corn produced in the barn-fed pigs ten and three-tenths pounds of pork, whilst each bushel given to the outsiders formed only nine and seven-tenths. This result of course clearly shows that a large proportion of the food given went to keep the outdoor pigs warm, instead of adding to their flesh. If the bucolic mind will only grasp this fact, we feel sure that more attention will be given to the question of shelter for animals.
