possesses many advantages—in fact, all the advantages of other pneumatic 
carriers, such as speed and a high degree of adaptability to crooked routes. 
Unfortunately, however, this pneumatic system is so expensive as to preclude 
its adoption in commercial elevators. I saw no evidence, in either Europe or 
Fig. 26.—Delivery spouts at the top of silos in a large English elevator. 1 is the lower 
art of the spout 2, shown in Fig. 25. Fig. 2 of the present illustration is another similar spout. 
By pulling one of four slides, as 11, the grain from 1 or 2 may be delivered to any of the silos 
7, 8, 9, 10, by aid of one of the spouts 3, 4, 5, 6. Of course, only the mouths of the silos are 
shown (7, 8, 9, 10, &c.), this floor being over the silos and some 80 feet above the ground. 
America, that elevators of this class were gaining ground, and, until invention 
finds a way of lessening the cost of this attractive system of transportation, we 
may leave it entirely out of consideration so far as elevators are concerned. 
Elevators in this State. 
While elevators and storage in bulk have not been extensively tried in 
New South Wales, there are some elevator plants the history of which should 
be mentioned. Over ten years ago Mr. J. Crago, of Bathurst, built a wooden 
silo or bin of a cubical shape, 30 feet deep, holding, therefore, some 20,000 
bushels. (Hig. 28.) 
Some three years ago Mr. Crago put up a flour-mill in Sydney, and in 
connection therewith he constructed, nee a year ago, an elevator of about 
70,000 bushels’ capacity, consisting of wooden silos or bins 8 feet across and 
47 feet peep. 
Both these ventures have proved successful, and Mr. Crago informed me 
that, in the latter case, he is sorry he did not make his elevator twice as large. 
No special difficulties due to climate have been encountered. The timber used 
in these two cases was ironbark and Oregon pine, and they have answered 
well.
