PICTORIAL SURVEY OF ESSEX. 3 results is to map out the country into districts and enlist as many local helpers as possible. Negatives would be taken by the local helpers and their friends, and prints by some permanent process, such as the platinum or carbon processes, would be made by them and forwarded to headquarters unmounted. Such prints should be accompanied by descriptive labels, giving information as to the object photographed, the date on which the negative was taken (this may be of the greatest importance), the process used for printing, and the name and address of the photographer. Whole plate and half plate should be the standard sizes for prints, but of course quarter plates would have to be accepted for hand camera work. These prints would then be carefully mounted, labelled and stored in such a fashion that ready reference would be secured. The Warwickshire prints are all mounted on card with sunk mounts, and are then bound into book form for storage. If the main object of the survey be, as it should be, the preservation of such records for future reference by serious students, this method seems to me to be not the best that could be adopted. Often reference to a particular district means referring to a large number of bulky volumes. Further, it is next to impossible to secure that card mounts shall be made of materials sufficiently pure to prevent the mount damaging the print; neither does the material of which such mounts are made possess the necessary lasting qualities. Suitable mounts can be made only out of the purest paper. The method of mounting and storage that I would suggest is illustrated by the sample shown by me at the meeting of the Essex Field Club in January last. The prints are mounted on paper of good quality, about the thickness of stout cartridge paper. All mounts are of foolscap size, and will take a whole plate, a half plate, or two quarter plate prints. Descriptive matter can be written on the back of the mount. The prints are attached to the mount by pure starch paste. The mounts are then bound together in a foolscap size "Stolzenberg" File, each photograph being protected by a sheet of tissue paper, bound in by the file between each mount. These files will hold about 50 to 100 of such mounts. They allow the prints to be examined as easily as though they were bound up like a book, and yet permit of the removal of any one
