The trays can be placed one inside the other and put into the box by the side of the bottles. The glass funnel should be turned over the top of one of the bottles, and unless the lantern is an extra size, there will be plenty of room to set it in the box. Nail a strip of leather across the box for a handle. A piece of board an inch or two larger all round than the top of the box will serve for a cover when the box is not in use.
With one's materials in this convenient and portable form it is a simple matter to get ready for developing, and when one has finished it is but a moment's work to replace the materials and put them away. This plan of storing materials not only saves a great deal of time and trouble, but often prevents mistakes in developing.
In preparing for developing get everything ready before the plates are taken into the dark-room. Always be particular to place the hypo trays in the same place each time you develop plates, and you will never make the mistake of putting a negative into the hypo instead of the developer.
Keep all the trays and bottles wiped clean. The trays should be thoroughly rinsed each time after using, so that no trace of hypo from the fixing tray may come in contact with the developing tray.
The amateur more than perhaps any other person should cultivate habits of neatness, carefulness, and exactness.
At all grocery stores east of the Rocky Mountains two sizes of Ivory Soap are sold; one that costs five cents a cake, and a larger size. The larger cake is the more convenient and economical for laundry and general household use. If your Grocer is out of it, insist on his getting it for you.
