EXPERIMENTS WITH H. M. STEAM VESSEL BEE. 
The Admiralty having ordered a small vessel to be fitted by Messrs. Maudslay 
and Field, it was resolved that the machinery should be so arranged so as to propel 
her either by paddle wheels or the screw of Mr. Smith. The engine (for there is 
one only) is of 10 horses’ power, and has paddle wheels attached in the usual 
way. The motion is communicated to the screw by an arrangement similar to 
the diagram fig. 57, which requires little explanation. The motion is transmitted 
Fig. 57. 
from the engine shaft first by bevel wheels and thence to the screw axis e by an 
endless band. The screw is constructed like that of the Archimedes. 
With this vessel the following trials have been made at the measured mile in 
Long Reach, the screw having been removed when the paddles Avere tried, and 
the paddles (or those of them which would have been immersed) unshipped A^hen 
the screAV was tried.
