448 THE PHOTOGRAPHIC NEWS. [September 17, 1880. second floor; so that, if there are many customers waiting, this circumstance is not rendered too obvious to the last comer, who might be frightened away if he saw the full extent of the queue. But the rooms are not only elegantly and comfortably fitted up ; they are so full of interesting pictures, that half-an-hour is quickly spent within their walls. Collodion enlargements on opal, collodion trans fers, and carbon prints are here in profusion—some per fectly untouched, others more or less highly finished in oil, and black-and-white, to suit all tastes and all purses. Here is a charming enlargement—two tiny sailor boys perched aloft on the truck of the main-mast among the rigging, with a clear-lit sea behind them. In the studio presently, we see the " accessory ” that has here been employed, an object of a very simple character, which is placed in front of a sea background, the seat being some five feet from the ground, so as give the effect of height. Not far off is another picture of interest—the portrait of a rough gold-digger in a Californian landscape. “ He came to us,” said Mr. B., “ with a yellow, stereoscopic picture, showing the spot where he made his fortune, and the wooden shanty in which he had lived during the making of it. ‘Here’s my diggings, and here am 1 my self ; now, can’t you make a portrait of me, and put me alongside the old place ? ” The Californian’s wish was gratified, and the picture before us tells how successfully the tour de force was accomplished. These are legal pictures. Here is a substantially built house, with two tumble-down cottages beside it. The owner of the house heard that his friends next door were about to pull down the adjoining premises, and build them up again on a finer scale; there was talk of a lofty estab lishment that bade fair to obscure the light of the house owner, so the latter conceived the happy idea of having the old buildings photographed forthwith, as they stood, so that in case of a law dispute about “ ancient lights,” good evidence should be forthcoming as to the actual height of the old dwellings. Another illustration. The nose of a ship has been damaged, and while it is lying in the dry dock, a photograph is taken to record the extent of the injury. It is the result of a collision, and there will probably be a dispute as to the amount to be made good. “This is the birthplace of Gladstone in Rodney Street,” said Mr, B. " An old lady living there objected to our taking the photograph ; we told her Mr. Gladstone was public property, and we should do as we liked. However, she was perfectly satisfied in the end, when we presented her with a copy of the picture.” There are, by the way, many fine pictures, on a large scale, of private residences, and we doubt whether there are many photographers who are so alive to the turning of an honest penny in this branch of business as Messrs. Brown, Barnes, and Bell. We go across to the printing and mounting establish ment, having first announced our coming through the. telephone. Nearly a hundred people are here employed, and Mr. B. tells us the number of employes and families dependent on the firm are scarcely less than one thousand. — think of that all you who despair of getting a liveli hood out of photography. Here are store-rooms for in coming and out-going packages; here is the frame-makers’ department, in which frames of all sizes are turned out by the gross, the firm’s business in club enlargements being especially great. Fartheron are the toningrooms; limo toning only is employed, and in washing, toning, and fixing the utensils employed are all of slate. In Mr. B.’s opinion there is not a cheaper and better material for the purpose than enamelled slate. The slabs are screwed together, and the joints made tight with white lead. The water in the baths remains clear and cool, and a utensil, two feet square, costs but twenty shillings. The outhouses and yard devoted to printing is a very busy scene. In the open, upright screens secure shadow, but there are conveniences for printing under any condi tions. You can easily tell the dry plates from the wet when they are in the frames; the former are black, the latter white. “ You don’t like dry negatives, Mr. Oliver, do you?” says our host; and Mr. Oliver, who has had charge of the printing arrangements for the past fifteen years, replies most emphatically that he don’t. We go upstairs, moving from room to room. Sensitiz ing, mounting, touching, and painting is busily going on. From the first floor we go to the second, and from the second into the roof, where the collodion enlargements are made. There is just as much bustle up here as down below. Coating, sensitizing, aud stripping is going on in a series of laboratories, and close by is the enlarging room. An opening in the roof receives the small negative, under this is the lens, and a table below receives the sensitized collodion plate. No sunlight is employed, but direct rays from the sky, and, under these circumstances, an enlarge ment is secured in ten seconds. There is no dark slide, the room being sufficiently gloomy to prevent the film taking harm when it is carried about; the negative is adjusted and focussed, and then the sensitized opal plate is brought from the bath, and laid on the table, upon which the en larged imago falls. After an exposure of ten seconds the plate is taken up, and developed. A hundred collodion enlargements a day are sometimes made in these labora tories. The “At Home” next week will be “ M. Lafosse at Knoll’s House, Manchester.” o FERROUS OXALATE BY SAMUEL FRY. The attention called to the simplicity of ferrous oxalate for developing by Dr. Eder’s formula, of solutions of oxalate of potash, and protosulphate of iron, gave a great impetus to what had, up to that time, been looked upon as a method of development rather in vogue by persons not very successful with pyrogallic. This was scarcely correct; the reason of its adoption, in spite of the difficulties, was because the resulting negatives resemble in colour wet collodion plates, and are free from the weak yellow appearance so often found in pyrogallic developing. It may not be uninteresting to record the results of several months of daily practice with Dr. Eder's formula, and certain conclusions arrived at. First, with regard to exposure, it may, the writer thinks, be accepted that about one-fourth longer exposure is required for ferrous oxalate development than for pyrogallic. This has been the result of a great number of comparative experiments. The strong point of ferrous oxalate with those who once get well to work, is the ease with which full printing den sity is obtained at the one operation, and yet, curiously enough, the great cause of failure is removing the plate too soon from the solution, and thus obtaining a very thin grey image. It takes some little practice, and, 1 may say, determination to leave the plate in long enough. The reason will be obvious on consideration why greater density is required than in pyrogallic development. In the latter the image is of a very non-actinic colour, whilst that of the iron is, as in the collodion plate, of grey-black. The addition of an organic substance to the developer has been recommended for years past, and the writer has very carefully considered the question of sugar in the ferrous oxalate, with the result of recommending it strongly. The best proportion is one-fourth that of the iron, and may be added to the stock solution of protosulphate. It seems to assist in developing by shortening the time, and giving more intensity, as well as in preventing the oxida tion of the solution which, when containing sugar, may be used for a much larger number of plates, with complete success. It has been objected that to anyone doing a large business, ferrous oxalate would be useless, on account of । the slowness of its action ; the very reverse is, however, the case. In my experience a photographer developing from eighty to ninety negatives daily finds he can put a
