FORESTRY AND IRRIGATION 



November 



Middle West to the benefits and possi- 

 bilities of forest planting. It is pro- 

 posed to have a series of lectures on 

 forestry given during the winter at 

 the farmers' institutes in Nebraska. 

 The lectures will indicate briefly the 

 steps which should be taken in plant- 

 ing windbreaks and woodlots, call at- 

 tention to the trees which will serve 

 both for protection and as a source of 

 timber supply, indicate how the plants 

 can be grown at home if desired, and 

 explain the cultural methods which 



value of the stream waters in the 

 state are rapidly nearing completion. 

 The work is being formed under a 

 joint appropriation, the California 

 part of which was authorized by the 

 state legislature at the last session. 



It was long since noted that the wa- 

 ter in California's streams is somewhat 

 peculiar in that its character varies 

 from season to season and often from 

 day to day. Therefore infrequent 

 analyses do not afford results upon 

 which dependence can be placed. A

should be given them. In the past, 

 many short-lived and worthless species 

 have been planted, and it will be the 

 aim in this work to call attention to 

 such short-sighted policy and to make 

 recommendations for the better selec- 

 tion of species.

water analyzed during the spring in 

 the period of freshet will by no means 

 have the same characteristics as an- 

 other sample taken from the same 

 stream would have during the periods 

 of low water. It is believed that there 

 are many streams in the State of Cali- 

 fornia which are considered objection- 

 able for household purposes by reason 

 of the alkaline ingredients which they 

 contain, which may, during seasons of 

 freshet, be found entirely unobjec-
