questions regarding the various crops: What is the yield per acre 

 in an average year, and what is the corresponding yield in seasons 

 when the rainfall is ample? The replies have been compiled, and 

 the averages are presented below as giving merely a preliminary indi- 

 cation of the possibilities of irrigation. Of course, damage by severe 

 storms and frost would affect irrigated and imirrigated crops alike.

CONCLUSION. 



The data presented seem to warrant the following conclusions: 



The irrigation of meadows and truck farms is an established and 

 profitable practice in the North Atlantic States, while the profitable 

 irrigation of field crops has not been demonstrated as yet. 



The methods employed are very expensive compared with western 

 practice, but are the outgrowth of peculiar conditions and meet the 

 requirement of very small applications of water. 



The quantity of water refjuired by truck crops either as rain or 

 irrigation is about I inch in depth every week, and in the light sandy 

 soils generally used it should be applied in quantities not exceeding 1 

 inch at a time.
