Thus 10 per cent of the cost of lining irrigation ditches 



can be eliminated by ditching with Austin Ditching Ma- 

 chines which excavate ditches with cross-sections cut ex- 

 actly to templet. These ditches are carved cleanly to shape 

 without disturbing the natural soil beyond the channel 

 limits so that no trimming or shaping is necessary and 

 very little cleaning is required to fit the earth cut for its 

 concrete or other lining. In addition, Austin Ditching Ma- 

 chines will dig ditches at a lower cubic yard cost than they 

 can be dug by any other means.
