Jun 10' Often as I have watched red clover, I have seen only 1 Hive Bee visiting it — Was tubes split? for I saw small wild Bee apparently split corolla. —

16' I have watched evening & midday green field of Red Clover swarming with Humble (& adjoining field of Sanfoin swarming with Hive Bees) & not one Hive visited red Clover— so good case for Ch. 6 my imaginary case. put note about one exception.—

I doubt whether Humble visit little Yellow trefoil — my old notes in Portfolio wd perhaps tell—

June 7' /58/ hive Bees visit Trifolium incarnatum, but never Mr Miner has remarked in America the common red Clover — yet whole flower of former rather longer than latter, but the tube of common red is about only 13/100 longer, yet this quite stops Hive-Bees, who never look at it — So I believe B. muscorum is only Bee which visits Vicia sylvanum (yellow), No No June 19' saw Hive Bee at several — This will do for Ch 6. especially if I find Clovers require Bees action — I do not doubt in this case presence of a plant might depend on Bees proboscis being 1/10' of inch longer

Humble of same species visit Common Red Clover.

[Cross and self fertilisation, p. 361: "An experienced apiarian, Mr. Miner, says that in the United States hive-bees never suck the red clover; and Mr. R. Colgate informs me that he has observed the same fact in New Zealand after the introduction of the hive-bee into that island."]
