Jan 5th * Of the 21 ash-petioles drawn in by base all except 3 ie 18 had thick end when leaf articulated with branch gnawed & this explains why so many there drawn in — Apparently many petioles are temporarily drawn in & then rejected for many lay strewn round holes — Some drawn in for protection of burrow & some for food — base thick & fleshy.

Jan 6 37 drawn in by tip, tips perhaps 6 gnawed — of the 42 drawn in by base, only 6 not gnawed. Of the 37 — drawn in by tip, 5 had previously been gnawed at base. I have no doubt the petioles are drawn in by base, gnawed & then pushed out of hole. The bases of petioles much enlarged.

Clematis I believe C. Montana — petiole thicker at base, but not enlarged like ash petiole — How are pet of Robinia Taper only moderately

Observation to test intellectual power of if such an expression may be used, or the discrimination of such lowly organised creatures as worms.

I doubt about pricking, though such was appearance in case of Pine leaves — as small rose-thorns, very sharp front of glass & hard score with very sharp projecting points

Jan 8th 1881 — Mem ash-trees in Field surface partly thickly strewn with old petioles; I picked up 47 petioles, where they lay with thick mud a casting; of the 47, 14 had been gnawed at the broad basal end (or a little above the articulation, as is often the case with those drawn into burrows). Thus sufficient to show that worms after drawing in petioles into burrows; reject them as not fitted for protective purpose as cannot easily for draw far down holes, for many of the 47 had partly fallen on surface & had never been touched by worms.
