also frequents the haunts of moles. These animals, when in pursuit of 

 worms, on which they feed, frighten them, and the worm, in attempting 

 to escape, comes to the surface of the ground, where it is seized by the 

 lapwing. The same mode of alarming his prey has been related of the 

 gull. 



NEW MOTORS, 



From that truly valuable journal, the Scientific American, we extract 

 the following account of new Motors, and we fully agree with the 

 writer in the belief that there is at present no prospect of degrading 

 steam from its present high position as the king of motors. 



♦' During the last few months we have enjoyed the pleasure of wit- 

 nessing the operation of three engines propelled by new agents never 

 before successfully applied to driving machinery. These are, the engine 

 of B. Hughes, in which the bi-sulphuret of carbon is employed as a 

 substitute for steam ; the " Cloud Engine " of Mr. Storms, in which a 

 jet of cold air is mixed with the steam ; and the third is the engine of 

 Dr. Drake, of Philadelphia, the motive agent of which is gas and air. 

 The bi-sulphuret of carbon engine performed in a superior manner to 

 steam in our presence ; but we only witnessed two experiments, and 

 have had no opportunity of testing it or seeing it tested under different 

 conditions; we were pleased, however, with its performance. The 

 " Cloud Engine," which was in operation at the Fair of the Americen 

 Institute, gave evidence, in our presence, on one occasion, of being more 

 economical than simple steam. How this was obtained by injecting a 

 jet of cold air with the steam into the cylinder, we could not divine, 

 nor did the explanations of the inventor satisfy us ; but its superior 

 performances have been indorsed by Horatio Allen, Esq., of this city, 

 an engineer of distinguished reputation. C. AV. Copeland, M. E., has 

 also been making a series of experiments with the " Cloud Engine," 

 and his report of it will, no doubt, throw much light on the subject. 

 Every improvement in prime motors is of vast importance, but the 

 advantages of any new engine must be clearly established before ifc 

 takes the place of steam, and we are of the opinion it will not be easy 

 to do this ; still, we hope it may soon be done, as we wish for and 

 welcome every new and useful improvement in science and art.
