straight line and the ditch actually cleans itself, so that it 

 is at all times ready to take care of heavy rainfalls. The carry- 

 ing capacity of a canal made by the Austin Drainage Ex- 

 cavator is from twenty to forty per cent greater than that 

 of canals of the same size made by ordinary methods. 

 The excavator is constructed of steel throughout and is 

 practically indestructible. While it is essentially an earth- 

 handling machine yet it will take out boulders, stumps and 

 roots if they are not too large, and being very srong it is 

 not apt to be injured by these obstructions. 



It propels itself upon a temporary track, and is so 

 arranged that it can be operated either backward or for- 

 ward, thus relieving the ditch of the weight of the ma- 

 chine. This is a desirable feature when passing over 

 swamps, bogs or light bottoms which are covered with 

 water when the machine enters them. In this country 

 nearly all drainage canals run through soft marshy places, 

 and in order to work to the best advantage there should 



be sufficient fall to the ground so that when work is com- 

 menced at the outlet the water will drain off ahead of the 

 machine and permit the soft ground to dry out before the 

 excavator reaches it. 



Instead of the above a rolling platform traction is 

 sometimes desirable, particularly where the yardage is 

 light, as is the case in the construction of shallow canals 

 and ditches. When so equipped these excavators require 

 but two men on the pay roll for each working shift. 



The capacity of the machine varies according to the 

 size of canal, but under favorable conditions, and charac- 

 ter of material with Type A machine, it is possible to ex- 

 cavate from 1,900 to 2,300 cu. met. in twenty working hours. 

 It is customary to have two operating shifts, one for day 

 and one for night work, but this output may be curtailed 

 or increased, according to the manv conditions which gov- 

 ern a given case.

TRUMP TURBINES 



When used for driving centrifugal pumps 

 for irrigating purposes, either direct con- 

 nected horizontally or vertical!* , or for 

 furnishing power through other types of 

 transmission, will be found to be the 

 most economical and highest grade type 

 of water wheel machinery manulactured 

 in this country. These turbines are 

 adaptable to the severest of conditions. 



We build all water power appur- 

 tenances, such as Head Gaes, Head 

 Gate Hoists, Piping, Etc. Send

SAMSON TURBINE! 



When the PUMP cannot be direct connected to the tur- 

 bine shaft, the power is usually transmitted by gears, 

 shafting, etc. On account of the HIGH SPEED of the 

 SAMSON, for a given power, lighter and consequently 

 CHEAPER transmission machinery can be used.
