in connection with steam pnmps." [The featnre stated is found in 

 tlie pump ; and it greatly simplifies the construction, but is liable to 

 the objection that an injury to or breakage of either cylinder destroys 

 both.'"'] 



In conclusion, we submit it to your honorable board that we have 

 shown not only by the practical test of 1867, as applied to the pump 

 of Knowles' and that of Hardick at this exhibition, but by the 

 "paper showing" of the parties themselves, that the Knowles direct- 

 acting pnmp of to-day is superior in all respects to the Niagara direct- 

 acting pump, not only for general purposes, but as a boiler feed. 

 We therefore recommend that a first premium be awarded to Messrs. 

 Knowles & Sibley for the best direct-acting steam pump. 



And finally we must state that we hardly feel authorized in decid- 

 ing that tlie Blake is superior to the Niagara pump, although it pos- 

 sesses several features which make it, like the KnoAvles pump, superior 

 in some respects to the Niagara pump, and though it possesses the feat- 

 ure of compactness which makes it superior in one respect to both the 

 Knowles and Niagara pumps. We sincerely regret that Mr. Blake's 

 pump could not have had a practical test similar to that of 1867, add- 

 ing however a test for all the pumps as to their capability for lifting 

 water ; but inasmuch as it was not subjected to a competitive test of. 

 this nature, we cannot innovate with a paper showing ujjon the rights 

 of the two pumps which have heretofore been subjected to such a 

 test. 



We, therefore, recommend that a second premium be awarded to 

 C. B. Hardick for a superior direct-acting steam pump, and that a 

 third premium be awarded to George F. Blake for a superior direct- 

 acting steam pump. 



Steam Ckank Pumi's. 



In this division there were two competitors, to wit : 



No. 729. Crank Pump and Engine Comlined. — C. B. Hardick, 

 Brooklyn. N. Y. 



No. 950. Woodward Steam Purnj). — Woodward Steam Pump 

 Manufacturing Company, New York city. 



These pumps were of the class which change a reciprocating into a 

 rotary motion by means of a crank. 



C. B, Hardick furnished us with a lengthy written statement con- 

 cerning his " crank pump and engine combined," better known as 

 the " Niagara crank pump," from which we cull and allow the fol- 

 lowing points of excellence :
