WHICH 15 REVOLUTIONIZING THE RECLAIMING OF ARID LANDS. 



Irrigation ditches are now made in an entirely NEW and SCIENTIFIC way. having for the 

 FUNDAMENTAL IDEA the making of a PERFECT, PERM \NENT WAl'ER-WAY.and 

 not the mere digging of a ditch with no thought nf NATURE'S laws. The worthless desert 

 may now be transformed, at small cost, into a GARDEN SPOT with the 



AUSTIN DRAINAGE EXCAVATOR 



It constructs a ditch, at a single operation, perfectly true to grade, of practically 

 any depth, width of bottom or width of top, and slopes the banks to any angle. 



The waste banks are built' at a distance from the ditch, and may be made 

 continuous to serve as dykes and increase the capacity of the ditch. 



Wide berms are produced, effectually preventing the waste banks from being 

 returned to the ditch from the action of frost or erosion. 



The excavating buckets travel in guide ways, transversely of the ditch, shaving 

 off a thin slice at each crossing, and truing the bottom and banks without disturbing 

 in any manner the original strata of the eatth. 

 With the banks undisturbed and exposed to the action of sun and wind, they dry out, producing a baked surfacing, impervious to 

 the action of the elements and practically indestructible a ditch is made scientifically correct in principle and HAVING THE 

 GREATEST POSSIBLE PERMANENCY obtainable in earth construction. 



IT CUTS THE SLOPES 



at a single operation, trimming them from guide-ways, absolutely true to specifica- 

 tions and removing every particle of loose earth. 



It is well known that Dipper Dredges cut vertical sides, tear up the bottom and 

 banks and deposit the excavated earth immediately adjacent to the bank. Exposed 

 to rain and frost, the banks cave and the waste banks are returned to the ditch by 

 erosion, requiring frequent cleaning out at an expense almost equal to the original 

 cost of the ditch. 



Government reports show that in irrigation ditches constructed by Dipper 

 Dredges, owing to the irregularity of the banks and loose earth remaining in the ditch, 

 the seepage from th* mains alone is frequently as great as 90 per cent, of the total 

 flow of water. In irrigation ditches where there is rapid flow of water containing a 

 large amount of silt, when the ditch is built with the Austin Drainage Excavator, 

 owing to the perfect construction of the ditch, the silt is not obstructed and the flow of 

 maximum -capacity maintained. The Austin Drainage Excavator produces a 

 permanent ditch which keeps its shape and at an ultimate cost of less than one third of ditches constructed and maintained by Dipper 

 Dredges. Write for Catalogue No. 5.
