FORESTRY AND IRRIGATION

AN ATTENTIVE CLASS TO A FIELD DEMONSTRATION. 



and also small sweet and yellow birches, 

 distinguishable mainly by taste. Or 

 take the program of a day with Pro- 

 fessor Tourney's class. After the early 

 morning lecture on the relation of rocks 

 to silviculture, all walked across the 

 Delaware River bridge into New Jersey, 

 to observe the tilted strata of limestone, 

 the character of the dark-colored soil it 

 forms, and the greater luxuriance of its 

 vegetable growth compared with that 

 on the disintegrated shale on the other 

 side of the river. Recrossing to the 

 Pennsylvania side, the class followed 

 the gorge of the Sawkill at the water's 

 edge, observing the layers of shale, 

 until it reached the still poorer land 

 abounding in boulders of Catskill sand- 

 stone and other stone of the glacial 

 drift, Professor Tourney directing espe- 

 cial attention to the effect of weather, 

 water, and tree roots in hastening the 

 breaking up of the rocks, and similar 

 matters. 



In the afternoon field work in forest 

 mensuration or laboratory work in. the 

 identification of plants occupies the 

 time, except on Wednesday and Satur- 

 day half-holidays, w r hen baseball reigns 

 supreme. The swim before supper is 

 seldom missed. 



In the evening a bonfire is kindled in 

 the open court of the camp, and expe- 

 riences of the day are exchanged, which 

 provoke the recital of similar adven- 

 tures in the widely separated regions 

 from which the students are gathered. 

 Mr. Gifford Pinchot attended one of 

 these informal gatherings, and spoke 

 concerning the government forest- re- 

 serve policy, the importance of state 

 forest maps in controlling forest fires, 

 the present attitude of cattlemen and 

 sheepmen in regard to grazing on the 

 reserves, and current work of the Bu- 

 reau of Forestry. Association with the 

 professors around the camp-fire is en- 

 joyed by the students, and is of much 

 practical benefit. Then, with the class 

 yell of " Ban-zai, Ban-zai " (the Japa- 

 nese war cry, learned last summer from 

 the Jap camp cooks), all would retire to 

 a well-earned night's sleep. 



YALE FOREST STUDENTS AT MILFOKD. 



To give more thorough training in 

 forest mensuration and silviculture, a 

 summer term was this year added to 

 the first year of the regular two years' 

 course at Yale. This is separate and 

 distinct in both lectures and field work 

 from the Summer School. Like the
