THE IRRIGATION AGE. 



CALIFORNIA-ARIZONA PRO- 

 JECT. 



Engineers throughout the country, 

 and especially those engaged in irri- 

 gation development in the West, have 

 been greatly interested in the pro- 

 gress of the construction of a remark- 

 able dam across the Colorado River 

 near Yuma, Ariz. 



This enormous structure, nearly a 

 mile in length, nineteen feet in height, 

 and 246 in width up and down stream, 

 was built by force account by the 

 Reclamation Service. It rests upon 

 the quicksands of the turbulent Col- 

 orado River, and is the only structure 

 of its kind in this country. 



Since its completion many promi- 

 nent engineers of the United States 

 and several from other nations have 

 visited the site. 



The erratic stream has several 

 times spent its fury in vain against 

 the obstruction which man has placed 

 in its channel, but the severe tests 

 which the dam has withstood are 

 evidence that it was built to say.

TheLittle Roadster Grader and Ditcher 



A New, Light Ditch Plowing Machine, 



Especially Designed for Cutting Small 



Laterals on Irrigated Farms, and 



Ditching and Grading Roads. 



This type of machine cuts ditches for 

 less money than any other tool or ma- 

 chinery, because it plows the dirt out of 

 the ditch with one continuous motjon, 

 whereas all other ditching machinery or 

 appliances must pick the dirt up and 

 lift it out of the ditch and then dump it. 



The Little Roadster is a practical 

 plowing machine, being built with ad- 

 justable leaning wheels or rolling land- 

 sides which counteract the side pressure 

 of the earth on the mold, the same 

 leaning wheel principle which^is used in 

 the sulky plow. 



It is made almost entirely of wrought 

 steel and the few castings that are used 

 are malleable and all parts are put to- 

 gether so far as possible with hot driven 

 rivets, so that while it is a light machine 

 weighing about eleven hundred pounds, 

 it is exceptionally strong and rigid. It 

 is designed primarily for two horses, al- 

 though four may be used. 



EVERY IRRIGATED RANCH OR FARM NEEDS ONE OR MORE OF THESE MACHINES. IT WILL QUICKLY 

 PAY FOR ITSELF. SEND FOR DESCRIPTIVE FOLDER AND LET US TELL YOU MORE ABOUT IT
