TREES AND TORRENTS 81 



her rapid growth and continues to maintain a corps 

 of engineers in the field. The reservoirs of the 

 present system have been built large enough to hold 

 the maximum run-off from all the surrounding 

 slopes, but the city has not entirely disregarded the 

 value of trees, and many acres about its reservoirs 

 have been afforested. Although it is much easier to 

 obtain tremendous sums for engineering works 

 which will tap and control a known water supply, a 

 number of our well informed men acquainted with 

 the European developments above mentioned, be- 

 lieve that forest planting and protection in America 

 would accomplish the desired object better and more 

 cheaply than an excess of reservoir construction. 

 While admitting the value of trees in this respect, 

 let us neither be too hasty in large scale experiment- 

 ing nor too backward to profit by the coming ex- 

 tension of forest growing and wood-crop cultivation. 



The city of Newark, New Jersey, recently ac- 

 quired a very large acreage in the nearby hills 

 contiguous to its water supply. Part of this area 

 already has a considerable forest cover and such 

 sections as need it are gradually being planted to 

 extend the great sponge which feeds the reservoir. 

 Incidentally, a fine park and recreation ground for 

 the people will thereby be created. 



Newark is going only a step further with an idea
