PHILADELPHIA, September 5.

Whatever has a tendency to enlarge the sphere of human action, deserves the fostering care of every enlightened state. It is therefore with pleasure we inform the lovers of science and the useful arts, that the ingenious Mr. Rumsey, who is now in Europe soliciting exclusive rights for his several inventions and improvements, has been honored with the esteem and support of gentlemen in England of distinguished reputation in the scientific world. We rejoice the more at these marks of attention to American genius, as they go far to prove the worth of Mr. Rumsey's talents, and afford an happy presage of honor and advantage to his native country.

Among the objects which have successfully engaged the abilities of this ingenious man are the following:

I. A Boat, or Vessel, acted on by steam, and propelled by forcing the water through a wooden trunk, or pipe, laid on the kelson. This boat requires neither masts, rigging, sails, oars, cranks or paddles, and has been actually propelled, with half its loading on board, four miles an hour, against the current of the Potomac river. It is light and simple, and may be built at a moderate expence. Where the rivers, like many in America, are unaided by the tides, and have rapid currents, the construction will appear to be singularly useful, by performing the passage in a given time, reducing the freight of goods, and promoting intercourse among the citizens in a convenient, cheap, and easy manner.

2. A new invented Saw-Mill, moved without wheels of any kind; requiring but about the twentieth part of the water used for a common saw-mill, and which may be applied either from a stream, a pond, or a well.—It is cheap and powerful.

3. A new boiler, for generating steam in the most convenient manner, for nautical, mechanical, and hydraulical purposes. This is confessedly superior to any hitherto discovered and may be applied to most kinds of mills and machines, at a comparatively trifling expence.

4. An improvement of Savery's admired mode of raising and conducting water.—Of important utility in agriculture and certain manufactories.

5. An improvement on Dr Barker's Mill. Dr. Barker was a Fellow of the Royal Society in London, and near half a century ago first suggested the principles of this machine; but he was never able to perfect it: being examined with anxious, yet fruitless solicitude, for its completion, by many learned societies in Europe, the plan was at length abandoned to the books alone as a monument of the Doctor's ingenuity; till lately, when the genius of a Rumsey discovered the right application of its principles. The mechanism of this mill is beautifully simple—the principles are strictly philosophical—and its powers are uncommonly great. A third, or fourth part of the water now ordinarily required to turn a grist mill, is sufficient, by this mode of applying its weight and force, to turn any grist-mill, or other machine, requiring the truest circular motion. The same powers will equally well apply to grist, saw, sugar, and most other mills—to rice machines, indigo works, and cotton gins. The water for this mill may be taken either from a natural stream, pond, or well.

Models of the Boiler, Water-works and Mills, are now in this city; and we learn with pleasure, that the latter have repeatedly performed to the admiration and entire satisfaction of many respectable characters who attended the experiments.
