IRRIGATION DITCHES 

 DUG READY TO LINE 



Loss of water by seepage or leakage in irri- 

 gation ditches ranges from 1 per cent, to 12 per 

 cent, per mile. To prevent this loss up-to-date 

 irrigators are lining their ditches with concrete, 

 but it has been found that a good lining a lin- 

 ing which will endure can be built only when 

 a food foundation or base is prepared for 

 it. The sides and bottom of the ditch must be 

 smooth and true to slope and grade, or the lin- 

 ing will be irregular in surface and thickness, 

 and, therefore, in strength. The soil forming 

 the^sides and bottom must, moreover, be as 

 compact as nature allows, or else the lining will 

 receive unequal support and crush in or crack. 

 Irrigation ditches are dug ready to line by the 



AUSTIN DRAINAGE EXCAVATOR 



Because the scraper buckets are guided by a 

 templet guide frame adjusted exactly to the 

 engineer's cross section of the ditch, the digging 

 is done true to grade and slope, and the natural 

 soil is not disturbed an inch beyond these planes. 

 The ditch is ready to line the moment the 

 Austin Drainage Excavator leaves it. This 

 machine digs ditches to templet in one oper- 

 ation. It moves along the work by its own 

 power.'* Send for our form letters and catalogue
