Reply to CD’s note ["Holly berries", Collected papers 2: 189–90] from a beekeeper: attributes the scarcity of bees to the harshness of weather in preceding spring.

Summary

Sends letter clipped from Manchester Courier on CD’s accounting for scarcity of holly berries by scarcity of bees, and writer’s explanation of latter.

Has sent new edition of Orchids – greatly altered, but he hopes improved.

Praise for Cross and self-fertilisation: most important point proved is benefit of crossing between related individuals grown under different conditions. This explains adaptive value of dispersal mechanisms.
