Reviewed in Jour. Am. Peat Soc. I: 21-22, and in Jour. Geol. I6: 584. 19o8. Besides covering the subject of Michigan peat, this is the most extensive work on peat in general which has appeared in this country in recent years. By order of the state geologist, nearly all the plants mentioned in this report are given "English names," which in the case of many of the rarer species are merely translations of the technical names, and therefore meaningless to the nonbotanical reader. The work contains an extensive bibliography, though most of the citations give no page numbers.
