THE IRRIGATION AGE.

condition that he endorse the plan; there are several irri- 

 gation systems where for each a million dollars or more 

 has been expended because the plans were approved by 

 Professor Carpenter; and many others constructed on his 

 approval where the cost was $500,000 and upward. 



Kansas brought suit against Colorado to stop the use 

 in the latter state of the waters of the Arkansas river, 

 demanding the uninterrupted flow of these waters into and 

 through Kansas. 



.Ten thousand pages of evidence were submitted to 

 the United States supreme court, and Colorado won after 

 an intense contest. The attorneys on both sides conceded 

 that the case was won solely through the mass of facts on 

 irrigation presented by Professor Carpenter and that with- 

 out his evidence Colorado would have lost. 



Had Colorado lost this suit, irrigation would have 

 ceased in the State along the Arkansas and an area of 

 highly productive land, equal in extent to all the improved 

 land of New England, would again have become a desert. 

 If Kansas had won, other states were planning to stop the 

 use in Colorado for irrigation of the waters of the Platte, 

 Rio Grande and Grand rivers.

SPRAYING IN GENERAL. 



BY H. E. STIVER. 



The subject of spraying has not heretofore suffi- 

 ciently engaged the attention of the fruit men of the 

 west, but, we are glad to say, they are commencing to 

 realize the great value of it, and a goodly number of 

 our prominent growers are using the pump and mix- 

 tures as a stepping stone to greater crops better crops 

 and bigger profits. 



This initial article is not intended as a treatise on 

 the technical side of spraying, but rather to show the 

 great possibilities which spraying presents, and to get 

 sufficient interest awakened to see if future articles are 

 desired by our readers. 



Stating it in the popular term of the day, "Spray- 

 ing is no cinch," as it requires careful planning and 

 plenty of elbow grease in case anything smaller than a

Carpenter to prepare a code of laws for that country to 

 govern all matters relating to irrigation and the appropria- 

 tion of water, and this code became the law of that coun- 

 try. The French government decorated him for work in 

 irrigation and irrigation engineering. 



The equipment of the Department is valued at $14.414. 

 and it cost $18.995 to operate the department for the two 

 years ending November 30, 1908. The enrollment in all 

 classes for the year ending March 1, 1909, was 614. 



The Colorado Agricultural College started the first 

 school in America in Irrigation Engineering and has been 

 sending out graduates from this department since 1892. 

 These graduates have been leaders in the engineering 

 world and many of them have done important work on 

 the irrigation systems of the state and have been and are 

 today one of the strongest factors in developing Colorado 

 agriculture. 



Several civil and irrigation engineers who have grad- 

 uated from this school have each had charge of construct- 

 ing irrigation systems that have brought more capital to 

 the state than the entire cost of the College from its be- 

 ginning to date.

The fundamental object of spraying is to both rid 

 and prevent the invasion of orchards, etc., by fungus 

 or vegetable parasitic growths, and by insect invasion, 

 these two main divisions of fruit enemies being classi- 

 fied as fungus and insect, and their respective pre- 

 ventatives and cures are known as fungicides and in- 

 secticides. 



Xearly everyone is familiar with the action of the 

 common tapeworm, which takes the strength giving 

 parts of one's food the part that should be used in 

 building up a strong body and appropriates this for 

 its own use. Constantly repeated, this operation in- 

 variably results in the loss of flesh and vitality, with a 

 consequent weakness. As the worm grows larger it de- 

 mands more food. At the same time the body tissues 

 are crying for their nourishment, which is being used 

 up by the parasite, and the intellectual and physical 

 strength of the man is in grave danger, as the sound- 

 est mind must necessarily require first a sound body to 

 draw from.
