Size Of Print. One should use large plates, if possible, for all commercial work, but if you do not desire to invest in an expensive outfit, you may use smaller plates and make enlargements from the small negatives, which can be very carefully worked up. Smooth bromide paper is the most satisfactory to employ for this purpose. Handwork on large prints will not show in the final reproduction, providing the illustration is much smaller than the print. The reduction in size does away with any slight roughness which might appear in the large original.
326. To further illustrate the methods employed in making photographs for catalog work, we have chosen for our subject the Gammeter Multigraph, which instrument is used to print duplicate type-written letters. This machine, instead of printing a character at a time, as does the ordinary typewriter, prints the whole letter, and to illustrate the method of working as clearly as possible, the manufacturers of this machine have in their excellently printed catalog shown the various steps from the setting up of the type on the machine to the printing of the letters.
327. In the accompanying illustration we show reproductions from the original photograph, as well as from the final worked-up print, which latter illustrations were used in the catalog. Illustration No. 66 shows the picture of the machine as supplied by the photographer. Illustration No. 65 shows the hand-work applied to the print by the artist, to give it a more even and uniform tone. This illustration shows the method of setting up a letter, the type in the left-hand cylinder being thrown, letter by letter, into the right-hand cylinder by means of a key, which the lady is pressing down with her right-hand thumb. The cylinder on the left side is revolved by the left hand until the proper type character is opposite the channel which leads onto the printing drum constituting the right half of the machine. The form is held in position on the printing drum, as shown in Illustrations No. 68 and No. 67. No. 68 shows the print as furnished by the photographer and No. 67 shows the results of the hand-work by the artist. No. 64 and No. 63 show the feeding of the machine for printing; No. 64 represents the print as received from the photographer and No. 63 the results after the print is worked by the artist. This illustration shows the operating of the machine. By turning the handle to the right the sheet of paper is drawn between the ribbon and a rubber platen, coming out on the opposite side of the machine, as shown in Illustrations Nos. 69 and 70, the latter representing the photographic print and the former the hand-worked print.
328. Carefully compare Illustrations No. 63 and No. 64 and notice how the upper portion of No. 63 has been blocked out, while the lower part has been vignetted. The object of placing the white paper on the table in front of the machine was to completely separate the machine from any support that might be considered a part of the machine, and also enable the engravers to vignette the cut more easily.
329. In Illustration No. 67 the objectionable reflections which occur on the little platform in front of the machine in Illustration No. 68 have been worked out, and the outline of the various parts ruled in white, so that they may be shown to their best advantage. By comparing these two illustrations you will see other portions which have been worked up with either the air-brush, white ink or India ink, the black being required in some places, while the white is used in others. By careful comparison of the different illustrations, you will observe the manner in which the prints have been worked up to produce the final results.
330. Another type of subject is presented in Illustrations Nos. 71 and 72. This picture illustrates the manner of photographing a gentleman's traveling outfit to be used for catalog work. In Illustration No. 72 is presented the straight print from the negative. Here, you will observe, an ordinary knock-down table was used, upon which the articles were arranged. A piece of white canvas was care-

In Illustration No. 71 is presented a reproduction from the picture after the artist had applied his work. You will readily observe, by comparing these illustrations, that all the engraver requires is a print with good, clear detail and sharp outline. From this print he builds his final results, either by working directly upon the print, or, as was done in this case, by making a bromide enlargement and then applying the work upon the enlargement. All portions are carefully outlined and detail worked in where it was not sufficiently clear. The background, as you will observe, has been practically removed, and in the engraving the print has been vignetted, thus giving a clear outline to the picture.
