cent pine, and 20 per cent hardwood and pine mixed. No allow- 

 ance seems to be made for mountain glades, rocky pastures and 

 urban areas in the land classification, or for conifers other than 

 pine in the forest classification, but the areas occupied by these 

 probably do not much exceed i per cent of the total. 



The relative amount of forest ranges from 63 per cent in 

 Garrett County, which is the westernmost, highest and rockiest, 

 to 19 per cent in Kent, which is in the fertile green sand marl belt 

 near the head of Chesapeake Bay. Dorchester County is 21 per 

 cent salt marsh, and the area of marsh is said to be increasing, 

 presumably indicating subsidence. If we assume that half the 

 mixed pine and hardwood forest is pine, the proportion of pine 

 in the forests ranges from almost none in some of the Piedmont 

 counties (which have the richest soils), to about two thirds in 

 the three southeasternmost counties (which are rather sandy). 

 The total stand of saw timber (9 inches and over in diameter) 

 in the state is estimated at nearly 4 billion feet, board measure, 

 or about 1,800 feet per acre; and it is apparently being cut 

 faster than it grows. 



This report answers almost every question one might reason- 

 ably ask about the forest resources of Maryland, except the 

 amount of any one kind of timber (for there are many species of 

 hardwood and several of pine, differing considerably in economic 

 properties) in the state or any part thereof. As the work is 

 statistical rather than scientific, it contains very little informa- 

 tion about previous literature, geography, soil, climate, etc., 

 but those matters are pretty well covered by other state publica- 

 tions, and this one will be a great help to any one who may 

 hereafter wish to classify the forests by regions and determine 

 the relative abundance of the several species of trees and cor- 

 relate them with environmental factors.
