casting, has plugged holes indicating the position of the upper cylin- 

 ders. Certain vestiges of the grade-climbing machinery are evi- 

 denced by several studs on the frame behind the rear driving wheels 

 and by the continuous drawbar on the tender with a slot cut in the 

 end sill. 



The true identity of the model had been lost through a misunder- 

 standing at the time it was donated, and for nearly 60 years its con- 

 struction has been credited to the donor, L. B. Davies. The 

 correction of this error would probably be of little comfort to Sellers, 

 considering the bitter disappointments the grade-climbing locomo- 

 tive and every venture connected with it held for him. 



When Sellers returned to Cincinnati in December 1848, he re- 

 ceived the news of the failure of his scheme to obtain the Panama 

 charter. Nevertheless, he still hoped to secure a test on that road 

 through the assistance of Allen, or Norris, if the latter should win the 

 contract. In any event others had voiced serious interest in its 

 adoption during the New York trials. To further these hopes, he 

 set to work to improve the invention itself and to devise new means 

 of broadcastinq; its virtues.
