V) prevent this tray from pressing upon the worms beneath, it should be propped up by small l)loeks placed under the corners. When lai'ge pieces of perfor- ated paper are used they should be handled by two persons. By cutting them into smaller pieces and using a transfer tray (Fig. 15) one i)erson can perform the necessary work with ease. Such a tray is most conveniently made about 13 by 10 inches inside. When the paper, which should be made about one inch smaller each way, has been covered with leaves, and the worms have come through the perforations in search of their food, the whole may easily be slipped into the transfer tray, and as easily taken from it in depositing the worms on another table. In gathering leaves for the worms it will be found convenient to em- ploy a bag (Fig. IG), so arranged that it may be attached around the waist like an apron. Two such sacks may be made from an ordinary meal bag. The worms should be made to spin their cocoons on brush so arranged as to form arches Ix'tween the shelves, as is shown in Fig. 19. For the same object the co- cooning ladder shown in Fig. 17 was devised in 1842 by M. Davril. It consists of two cen- tral supports, across each side of Avhich (Fig. IS) are nailed small strips of about one-quarter by one-half inch section, li inches apart. The strips on one side are i^laced opposite the spaces between the strips on the other side. The ladder may be made about 30 l)y 15 inches, and the central supports about five-eighths inch thick. When in use the ladder is placed slantingly between the tables, with the central su])i)orts horizontal. A thermometer is a very useful adjunct to the appliances above de- Fig. 15.—Transfer drawer (after Koman).. Please note that these images are extracte
