LXXXIV. T. ROOKE. 
circumstances, which may be referred to, but cannot be 
fully dealt with, in the scope of this paper. 
It is intended, therefore, first of all to give an account 
of the irrigation works seen in California, more particularly 
those operated from electric transmission lines, and then 
to consider some of the possibilities in connection with 
sucl work in Australia. On reaching New York last 
March, I got into touch with the: General Hlectric 
Company, and the Westinghouse Company, who kindly 
furnished letters of introduction to their agents in 
California. On reaching California, these gentlemen made 
the necessary arrangements for visiting the irrigation 
works in the San Gabriel Valley, the San Joaquin Valley, 
and in the neighbourhood of Bakersfield. Several days 
were spent driving through the country districts in order 
to see these irrigation works, and to photograph pumping 
stations operated electrically, as it was felt that such 
photographs would be the strongest testimony possible to 
obtain. 
Pomona was the first township visited, and an hour or so 
was spent examining the deep well pumps made by Messrs. 
Addison, which are ingenious and simple. There are two 
concentric pump rods operated from 2 cranks placed at 
180° apart. On the end of each pump rod is a bucket 
provided with clack valves arranged as a cone. As the 
crank shaft turns, the two buckets alternately approach 
and recede from one another, and by so doing raise water. 
The buckets are easily lifted out of the well and replaced. 
The pump barrel is a stout tube some 10 inches in diameter, 
and fits closely into the well casing. It really forms the 
last length of a casing inside, and concentric to the well 
casing. It is readily raised or lowered for examination 
and repairs. This was the only form of deep well pump 
seen in use, and it was seen in all the pump-houses in the
