 THE IRRIGATION AGE, 30 N. Dearborn St., Chicago, 111. 



Gentlemen : The enclosed clipping from the Denver 

 (Colo.) Republican, relating to the development of Para- 

 dox Valley in San Miguel and Montrose Counties, is sub- 

 stantially correct. 



The construction of the irrigation works required, in- 

 cludes about twenty miles of heavy rock work, about 10,000 

 feet of tunneling, three inverted siphons (the longest being 

 about one-half mile, maximum head 500 feet), two reser- 

 voir dams, the larger being 175 feet in height; in all about 

 100 miles of conduits, ditches and laterals, and at least 50 

 miles of narrow gauge railroad. 



Yours truly, 



ROBERT M. F. DOBLE, 



Chief Engineer, 

 Placerville, Colo.

One Irrigation a Year 



By using the Campbell System of Scientific Farming 

 you can produce a bumper crop on one-half the water 

 ordinarily used. It is done by better tillage and a 

 thorough conservation of the moisture and plant food. 

 Many irrigationists are developing their orchards and 

 maturing their fruit on one irrigation a year by employing 

 the Campbell System storing the water in the soU. This 

 system prevents leaching, and keeps the soil fertile and 

 sweet at all times. You are not bothered with alkalinity. 

 Your land is never water-logged, thus depriving the plant 

 of the necessary air to insure a quick healthy growth. 

 Plants do not grow while the soil is water soaked. 



The Campbell Correspondence School 



is the result of thirty years' experiment and demonstration 

 by Prof. Campbell and his associates. This course teaches 

 when to plow, how deep to turn the ground, all about 

 cultivation, and the time WHEN and HOW to do the 

 work. 



THE CAMPBELL SYSTEM is used the world over. It 

 is practiced in Spain, Hungary, Italy, India, Australia 

 and North and South America. Wherever intelligently 

 used, by irrigator or dry land farmer, it has doubled the 

 yield.

Irrigated 

 Farm and 

 Fruit Lands 



The Northern Pacific 

 extends into or through 

 Minnesota, Wisconsin, 

 North 'Dakota, Montana, 

 Idaho, Washington, Ore- 

 gon. Nev>, rich territory 

 being opened up by exten- 

 sions now building. The 

 Homeseeffer's Chance! 



The small irrigated farm or orchard means greater production with less labor. It takes 

 away the element of chance and makes a good crop a reasonable certainty. The land 



in the Northwest such as is being irrigated by govern- 

 ment and private projects in Montana, Idaho, Wash- 

 ington and Oregon, on or reached by the Northern 

 Pacific Railway, is exceedingly rich and requires only 

 moisture to yield bountifully. This moisture is pro- 

 vided by irrigation, which makes irrigated farming, 

 fruit and vegetable raising a scientific profession, not a 

 drudgery. The ideal climate is a strong argument in favor of the 

 Northwest. 



If you want to know more about the possibilities of making yo^ur efforts bring 

 you greater returns, write for information about these irrigated ands. Maybe 

 the "dry farming" territory will interest you. Write tonight and state what section 

 you are most interested in" Don't delay. The information will cost you nothing 

 and will pay you well.
