19th To my astonishment I saw this morning, very many Hive-Bees visiting Red Clover, which is now partly out of flower, most were sucking at edge of calyces of flower in which corolla was partly withered — many others inserting proboscis into tube, but it seemed as if honey was very abundant & so many have half filled tube. — I strongly suspect their visit owing to adjoining field of San-foin having been cut; if so good case of flower affecting flower, if it turn out visits of Bees necessary for fertilisation—

At noon (19th) I again watched Hive Bees generally at work at calyx, but often in tube. — I may safely say get honey with difficulty & not till pressed by sanfoin cut down. — (I think this makes case better for me.— Mem. Miner says Hive-Bees never visit red-clover.— (Same day I visited Mr Ainslie's Stony field, with very much Red Clover, but also much Lotus, some Sanfoin & white clover, all these were visited profusely by Hive-Bees, but not one could by long watching see on Red Clover, & this really almost proves my theory of San-foin cut down. Excellent case of correlation.
