August 17, 1883. J THE PHOTOGRAPHIC NEWS. 517 varnish, the pictures, as I think they are more beautiful and artistic when simply finished with wax paste. After four- teen years’ experience, I can speak with a considerable de gree of confidence regarding thestabilityofcollodio-chloride pictures. I am not, however, prepared to assert that out of the many thousands of photographs which have left my hands throughout the course of these years, none of them have faded. At first the manufacturers of collodio-chloride papers were not so careful as they are now regarding the basis on which the collodion film rests ; nay, I have reason to believe that sheets of albumenized paper were then used -as a support for the emulsion. In such a case, the prints made from those sheets are liable to fade. But, notwithstanding this, the fact remains—and I am glad to be able to say so—that out of many dozens of photo graphs in my possession, dating back to the year 1869, 1 do not find any fading prints among them. Some of these prints have been lying loosely on shelves in a room where 1 have made up developers, boiled negative baths, made chloride of gold, toned, washed, and rolled my photographs for nearly a decade of years, and yet, so far as I can judge, they still retain their pristine purity. With reference to 12 by 10 framed prints, I may remark that those I forwarded to the Loudon Exhibition in 1874, and which were afterwards returned to the International Exhibition held the same year, and hung there along with other exhibits for some months, if I remember aright, in one of the corridors, exposed, as was remarked at the time, to atmospheric influences which severely tested the keeping qualities of the pictures, have not the slightest appearance of fading about them. Then, as regards what may be called independent evidence in favour of the stability of collodio-chloride prints in warm climates, I have to say that ladies and gentlemen who were photographed by me before they went out to India, or had prints of their friends sent to them when there, state that while albumenized prints often fade very rapidly, collodio-chloride prints continue un changed. Although I write warmly in favour of the collodio- chloride process, as being worthy of a better place than it has among the various printing processes connected with photography, I am not to be understood as having any money interest in connection with the sale of the paper. At one time I did supply photographers with paper, but ultimately gave up doing so. If, therefore, any gentleman wishes to' try collodio-chloride printing, he will require to order the paper direct from either of the manufacturers already referred to. TRANSFERRING PRINTED TITLES TO NEGATIVES. It is frequently desirable to print a title to a photograph, and from a practical point of view it is very much more desirable to so imprint the inscription upon the negative that each proof, whether unmounted or not, shall bear its own title, than to lay in a stock of specially printed mounts for each subject. As few persons possess the accomplish ment of writing in a reversed direction with ease and ele gance, it is not much use to recommend our readers to write their inscriptions backwards on the varnished film ; but we will rather describe a simple and easy method by which letter-press titles may be transferred to the surface of the varnish. The titles are printed on thin paper w hich has been evenly smeared over with moderately stiff starch paste and allowed to dry, a rather large amount of print ing ink being used in inking the type. Of course the photographer can get this printing done for him by the nearest letter-press printer, but as a title generally con sists of but two or three words, it is, perhaps, more gene rally convenient for the photographer to print them him self. There is a stock article at the London toy-shops, which consists of a wooden press, together with one alphabet of small type, also ink and dabbers. All these are sold retail for one shilling and sixpence, and if a simple alteration is made in the set, it becomes well adapted for the work now under consideration. This altera tion consists in casting aside the single alphabet of type, and replacing it by such a small fount as can be bought from Squintani, in Farringdon Street, for about eighteen pence. The single alphabet is useless, unless in the case of a title in which one letter recurs ; but the letters of the fount are so proportioned as to meet ordinary needs. Let us now suppose that the title is printed on the starched paper, and that the superfluous edges of the paper are trimmed off. The next step is to lay it, face down wards, on a convenient part of the varnished negative film, and to establish contact between the viscous printing ink and the varnish by gentle pressure, care being taken not to so move the transfer as to occasion the least smearing. The back of the paper is next slightly moistened, and the pressure is renewed, after which the paper is wetted suffici ently to thoroughly soak it. No difficulty will now be experienced in slowly stripping off the paper, so as to leave the reversed inscription on the negative; the last trace of fibrous material being removed by careful scrub bing with a camel’s-hair brush. When the whole of the water has evaporated, it is easy to reinforce the fatty letters by dusting over with finely-powdered red lead, all excess of this being wiped off with a soft brush. This red lead serves to render the inscription more opaque, and also expedites the drying of the fatty ink. The whole process of thus transferring printed titles to the varnished film takes a very few minutes, and generally the work looks much neater than if written. We need scarcely say that the transfer must be made while the ink is wet. A much less satisfactory method of titling negatives consists of simply gumming on a printed title, and leaving the paper in position. Similarly, the titles may be printed on a transparent material, such as thin sheet gelatine, and this may be left on the negative; but such expedients seldom make neat work. Just in the same manner as the typographic impression is transferred to the negative, an impression from a litho graphic stone or a copper plate may be put down on the varnished film. Should the ink be hard (a circumstance likely to occur when an impression is taken from a plate), it may be softened by being held over the vapour of some turpentine heated in a spoon. If the photographer should wish to avoid using type, he may photograph any title that pleases him, and make a photo-lithographic transfer from it, and put this down on the negative just as we have described in the case of the impression from the type. Major Waterhouse’s papers give full details as to making the transfer. THE TOURIST PHOTOGRAPHER. II.—The OETZTHAL Glacier. From Fend, we march direct to the glacier. There are two ways across to the Schnalser Thal: by the Hoch Joch, and Nieder Joch. Strange to say, the latter is some three or four hundred feet higher than the Hoch Joch, both of the passes being between nine and ten thousand feet above the level of the sea. For ourselves, we passed the Nieder Joch across the most lovely snow fields, and by glittering slopes of the purest white. Following in the footsteps of the guide, we traverse the shoulder of one sugar-loaf mountain after another, making a path for ouiselves in the soft, white soil, and looking down sometimes from our narrow track into a mass of cloud that concealed from the eyes the depth of the abyss below. Look steadily before you, and mind your footing, keeping your Alpine staff on the inside, between yourself and the mountain wall, is the best advice we can tender in these circumstances ; if your pole slips then, you fall against the mountain side, and there is no harm done. Again, never contemplate the scene below you while walking on these
