Obtain a box measuring about eighteen niches each way, place it in a larger box, and fill the space between the boxes with dry sawdust; place the ice in the inner box and surround it with dry saw- dust; enclose the soaked seeds in a piece of mosquito netting (to prevent losing them) and place them on the ice; cover them with moist sawdust (the melting ice will keep it continually moist). Fifteen pounds of ice will last several days under these conditions. Place other seeds of the same sort under water: it suffices to simp

Fifteen pounds of ice will last several days under these conditions. Place other seeds of the same sort under water: it suffices to simply put the seeds in a bottle, which is then submerged in water and tightly corked while under water, taking care to exclude all air-bubbles. Vaseline may be smeared over the cork to make it air-tight (Fig. 12). Air may be expelled from the water by boiling it for several minutes just before using, but. 11. Arrangement for keeping seeds on iee: the space between the boxes is iilled with sawdiist, which also surrounds the ice. 12.
