to the camp organizer, whose most perplexing ;task is the ordering of 

 subordinate items, which in the aggregate represent a considerable 

 proportion of the total expenditure. Experience shows that care 

 should be exercised in not ordering too large a stock of provisions, for 

 it is, as a rule, easier to replenish the stock than to dispose of surplus. 

 It also pays to buy vegetables, eggs, butter, and fresh meat from local 

 farmers, if possible. The quality is usually better and the prices lower. 

 A general summary of the tree-planting camp operations on two 

 State forests during the spring planting seasons of 1915 and l!)Hi 

 follows :

Xo planting cost is complete without an accurate and complete de- 

 scription of the existing growth upon the planting site. A dense and 

 especially a thorny or vine growth impedes the progress of the plant- 

 ing crew. A thorny or briary growth is destructive to the clothing 

 of the workmen, and makes planting uncomfortable, and, to a degree, 

 hazardous. The density of the existing growth is a vital determin- 

 ing factor of the spacing of the trees, i. e., the number planted per acre, 

 which in turn is a potent influencing factor upon the cost of planting 

 per acre and per thousand. 



A wide range of growth conditions is usually present upon such 

 extensive planting sites as those given in the preceding tabulation 

 In order to facilitate description the growth present upon such plant- 

 ing sites can usually be grouped under a few distinctive types. The 

 existing growth upon the 567.9 acres, comprising the area planted 

 upon the Black Forest State Forest during the spring of 1916, may be
