How the West isn't one
The author of "Why So Dry? Ocean temperatures alone don't explain droughts" (SN: 2/10/07, p. 84), seems to feel, like most other writers do, that "the western United States" properly covers all geographical bases. Believe me, the Pacific Northwest is anything but dry. One other point about geography: Weather phenomena, and other stuff, occurring in the Dakotas, Nebraska, Oklahoma, Texas, or Kansas are not happening in the 11 westernmost states.
The word on worms
I enjoyed reading in "What's Going on Down There?" (SN: 2/17/07, p. 107) about the marine census that's been taking place, but I was waiting for some mention of the organisms' parasites. Granted, worms are not glamour-pusses, but they are fascinating creatures. If we want a complete survey, they must be included.
