July 21st— Hartfield— saw in almost every Buttercup 2 or 3 small flies of more than 1 sort sucking anthers.

(With respect to possibility of intercrossing, carrying pollen from flower to flower it may be seems probable that Diptera, as far as number of species concerned, are more important than Bees— But not so interesting — they usually harvest uninteresting flower, which from no peculiarity of structure I have only lately attended — But when I have picked out insignificant flower & attended to it, & have usually found it visited by flies dusted with pollen. — Tormentilla — Buttercup

It Jul Stellaria — Spiræa some species— Saxifraga Euphoria odd flower, so the fly on Vicia hirsuta — Galium saxatile real difficulty, give case of G. palustre — G. aparine only a shade less difficult, for I saw only small yellow flower in one place late in evening.—
