Dart makes this statement because Evans invented the endless canvas or leather belt to which were attached buckets for taking up the grain through a leg. But Dart improved greatly upon the Evans' idea and it is to his credit to say that it remained for him to apply 'the Evans principle to the lakes. He was met with the rankest ridicule_when he started in on his elevator, and it might be that years would have elapsed before it was adopted if he had not taken it up. Evans had to contend with many obstacles in his day to work out his. endless bucket and horizontal convey- or ideas. Joseph Dart relates that he was a natural-born mechanic who stud-. ied way into the night by the light of shavings when refused candles by his employer. As the result of all his study 23 and Jabor, he gained the . knowledge necessary to write "The Young Miller's Guide and Millwright's Companion," still considered a standard work. Evans tried to introduce his elevator on the banks of the Delaware in 1785, but failed, and he afterwards had to defend his title to the invention. He also invented the method of keeping flour in motion and exposed to the air till thoroughly dry and ready for pack- ing. Dart's elevator was the first struc- ture of its kind in the world, being then known as a steam storage and transfer elevator. From "all accounts, 'it was the first to be operated success- fully, though there is brief mention made of one built at Black Rock in. 1840 by Lewis. f. Allen and: a: Mr. Lord.

The only mention found of this elevator are the names of the de- signer of the machinery, Robert Dun- bar, and the makers, Jewett & Root. It could not have been successful, how- ever, for if: it, had, the grain, traffic would have been diverted there. If Joseph Dart had lived in the mid- dle ages he would surely have paid the penalty of his seeming folly in erect- ing his elevator, but as it was he had the extreme satisfaction of living when and where there was no danger of be- ing sacrificed for individual effort. His initiative bore fruit a,thousand fold, and it appears that. thirty days after his elevator was in operation, one of the doubting Thomases among the Buffalo forwarding merchants came to him and offered double his regular rates for emergency accommodation.
