Rt hand worm Oct 8th 1880
Saw him drag several near the hole by the middle & try to get them in by the doubling them. I could see the mouth swell up into a lump I think he succeeded in getting them into the mouth of the burrow
Saw him seize 3 by the bases, he seemed to come across the base in the course of his circumnutation & then I fancied he seemed satisfied & gave a big pull in towards the hole one needle would not come, the other two went right in — He completely swallowed the burnt end of one. I saw him seize hold of the sharp end of a needle & then leave go.

Oct 8th
Left hand worm, reared himself up & seized the base of one whose apex was partly in his hole, he gave a strong pull & got the base at last to the beginning of the burrow doubling the needle somewhat
Saw a Rt hand worm swallow the base of a needle & then wave his head about for some seconds & then reject it. The Left worms seem less sensitive to yellow light, I watched them for some time with a taper
Oct 9th one drawn in by apex with other worm outside. Is Scotch-fir endemic in S. England? The above worm collected out of mould near formation & at apparent end of K. Garden, so may have learnt —
On 2 days pulled at leaves out of burrows on walk & each time on pulling many very many stuck again into burrows — very industrious.
(At present, considering all sorts of leaves I think worms by touch, judge of general shape & act accordingly so as to draw them in easiest ways into burrows.)
(A very young worm as those of fir [string] burrow in one of my pots, dragged a Scotch-fir leave, as long as its own body.)
(Oct 11th, saw worm seize hold of burnt end of pair of needles going near the hole & jerk it rapidly into burrow & it seemed to know that it was a proper position to go in.
Removed similar case.
