Orange Gourd. Dec. 17 & 18th /77/

Traced on Horizontal glass in Hot-House— protected from light.—

Dec. 17th Arc of hypot. cot just visible on a little beneath level of ground —, cleared away soil from little little above .2 of inch way all round to depth of about rather more than .2 & fixed glass filament rather obliquely to basal part of stem with shell-lack & placed triangle on ground. The filament dropped off on 2d day but I believe was about 1/2 inch from mark & as Horizontal glass was was 12.75 inches, after filament affixed, hollow filled up with crumbling earth, except minute conical hollow round base of filament.

[insertion:] I then tied with sil silk the apex of stem bearing the Cots to the basal parts.

Diagram magnified about 25 times. The first great movement between 9° am & 3° 4° 15 was zig-zag. showing tendency to [illeg] "circumnutation", but was chiefly the bending of the basal part from the seed & from the side where the Cots lay— If this had not be tied no doubt they wd have risen, owing to the unbending of the arc. From 3°. 5' to 6° went to left & then came back to 8° 15' & then back again to 10° 10'. Here we have clear circumnutation — Course during night shown by broken line, but no doubt nutated. By 10° next day (18th) the Cots. were out of ground & now fine circumnutation was exhibited, reaching by 10° P.m, nearly same spot as on previous night — By this time basal part of stem had grown greatly.
