FARM DEVELOPMENT 



family farms deals with small units, hence a professional 

 class of rural engineers skilled in this work has not yet 

 been established. As yet there is a comparatively small 

 number of engineers prepared to earn the fees which 

 wealthy men are willing to pay for plans for the organ- 

 ization of their large estates. The basic data are being 

 wrought out which will eventually so serve the man 

 trained in using water and in organizing irrigated 

 farms that he will be of great assistance to 

 the general irrigation farmer. The support of such men 



at public expense is 

 coming to be recognized 

 as a very proper way of 

 providing a certain 

 kind of teaching called 

 demonstration farming. 

 The farmer, the expert

rural school, co-operating, can often work out a plan for a 

 new farm, or can plan for the reorganization of an old 

 farm. The students of the consolidated rural and 

 village school can have the benefit of the various steps 

 in devising the plans, in developing the farm under the 

 new plan, and in studying the figures and facts re- 

 sulting from putting the plans to the test in the pro- 

 duction of crops and in the yielding of profits to the 

 owner. 



In Figure 145 some features of irrigation are illustrated 

 by means of a drawing showing a model plan in plaster 

 of paris exhibited at the World's Fair at St. Louis by the 

 American Association of Agricultural Colleges and Ex- 

 periment Stations. The water is represented as con- 

 veyed through a main canal to a reservoir and from there 

 conveyed through a continuation of the main canal, main
