Worcester County is the largest in the state (1,565 square 

 miles), and the field work occupied the author and nine students 

 three summers. Each man took one town at a time and ran 

 parallel lines across it half a mile apart, noting the extent of 

 cleared land and each kind of forest traversed, and putting the 

 results on a field map. The forests are divided into seven types 

 and each of those into four size classes. 



Of the total area of the county (which had 256 inhabitants per 

 square mile in 1910) 57 per cent was found to be wooded, 21 

 per cent tilled, 10 per cent open pasture, 5 per cent brush 

 pasture, and the remainder alder swamps, water, settlements, 

 etc. For each town similar data are given, together with notes 

 on wood-using industries, averaging about a page each. Nearly 

 a third of the forest is a comparatively worthless second growth 

 of gray birch, sugar-maple, swamp maple, and an occasional 

 oak. In the better forests white pine and chestnut seem to 

 be the prevailing trees, the former mostly northward and the 

 latter southward. 



If the field workers had classified the standing timber bv spe- 

 cies, which are pretty sharply defined, instead of by forest types, 

 which often grade imperceptibly into one another, it might have 

 added very little to the cost of the survey, and the results would 

 have been more useful, not only to manufacturers who might 

 desire a particular kind of timber for a special purpose, but also 

 to botanists and other scientists.

Forests of Maryland* 



The author, who is the state forester, sums up in this neat 

 quarto volume the results of seven or eight years' work. He had 

 contributed a chapter on forests to the "Plant Life of Mary- 

 land," published by the Maryland Weather Service in 1910,!
