fore used for steering ships, wheu the helmsman is placed near the 

 nidder. 



No. 628. Models of Yachts. (David Kjrby.) Several models 

 of yachts. The best on exhibition. 



No. 627. Model of a Boat Detaching Apparatus. (Samuel 

 Brown.) There are four models of boat detaching apparatus. Of 

 these the one, in the judgment of the committee, possessing the 

 highest merit, is No. 627, known as Brown <fe Levil's patent. The 

 judges are not only of opinion that it is the best model on exhibi- 

 tion, but the best known to the public. 



• No. 775. Working Model of a Steering Propeller. (F. G. Fow- 

 ler.) This method of propelling and steering a vessel is novel, and 

 in the absence of any experience of its qualities and merits, the 

 judges are not prepared to express any decided opinion. If, on 

 trial, it shall be found free from any serious defects in mechanical 

 arrangement and combination, they are of the belief that it may be 

 found valuable for canal and river purposes, and they therefore 

 hope to. see it put into practical use on a scale sufficiently large to 



test its merits.

To the Board of Managers: 



Gentlemen — The undersigned judges in Department VI, Group 

 • 3, report that they have carefully examined the several articles 

 referred to them. Taken collectively, these specimens of skill and 

 ingenuity furnish evidence of continued advance and improvement 

 in the methods used to accomplish a desired end. In deciding 

 upon the comparative value of the samples entered for competi- 

 tion, gi-eat scrutiny has been exercised, in order to weigh, impartially 

 the evidences of utility found in each. The following is the result 

 of the deliberations of the judges: 



No. 1141. Telegraphic Ilela3% (L. Bradley.) Relay wound 

 with naked copper- wire. As we regard this method of winding an 

 electro magnet an important advance over the ordinary method, 

 since it puts less resistance in the line for the same strength of 

 magnet, we would recommend a fii-st premium. In the same case a 

 "tangent galvanometer and rheostat" taken in connection, give an 

 easy and satisfastory method for testing the strength of electric
