Smell

(Sept 19 Pot II buried slice of onion — 22° onion discovered & dragged to surface & apparently gnawed, & after another day dragged down hole beneath surface of earth.)

(Sept -23rd Pot II. first bit of onion — 25° discovered & dragged from beneath earth.

(Sept 25. Pot. II buried cabbage with tin-foil below to prevent burrowing from below — removed same night.)

Sept 26. Pot II buried cabbage in same spot over tin-foil — 27° removed also a piece not removed)

27th passed earth slightly over it & over the others & watered both, so as to prevent worms feeling the cabbage with tips of body, if by chance it pushed its tips in the place

28th a.m both these bits of cabbage food & removed

28th red cabbage in both, 30° removed in Pot 2, but not eaten
