Description of Mr. Evans's Alill.[March

Stil! dove 50, but from having noticed that the plan of the ele- has been mentioned in a paper of one of the volumes

of the Society of Arts, as having been adapted for raising either r water, 1 forget which, I am therefore led to hope that

M)'bour may have been mistaken, and that the enclosed | useful. 1 was in Mr. Jonathan Ellicott's mill near ore, and in that of Mr. Nathaniel Ellicott, at Peters-

burgh, in Virginia; the former Seemed to have been an old mill, altered to Mr. Evans's plan, and the latter, a very large 1D2w vne, constiucted entirely upon It, and the proprietors who Shewed me over their mills, assured me that they were well ßed witb the plan, and considered it a great Improvement mil] machinery; and, I need not add, that the Brandywine ills which are mentioned in the enclosed, are considered as aferior 10 none throughout the United States. Whilst on e Subject of mills, I eannot avoid mentioning Something of ihe Sort[ met with at Boston, in the province of Massa- , which was called a Steam jack, and wbich I was in- duced particularly to notice, from the Steam being applied to the first motion in a way different from any 1 bad ever Seen or beard of, and though apparently of a Simple construction, as I am unacquainted with machinery and wechanics, and being unable to give you a drawing oft, 1 fear 1 Shall.be un- able to give you any tolerable idea ofit. Thefirstmotion,(which was the only one 1 particularly noticed,)-was a cast iron wheel about a foot in diameter, Similar in Shape to the water wheel of an overshot mill, the buckets. gf which, forming a pretty acute angle with the wbeel, apd the Sides of the wheel

„coming up Somewhat higher than the upper edge of the

buckets, the Steam-kettle which might contam about two gallons, was placed on a chafing dish of coals near this wheel with a spout, the upper part of which was rather Jonger than the under, and, near the width of the buck- ets, and the upper edge of the spout fixed. as near to the upper edge of the buckets as it could be done, witbout touch- ing either the edge of the buckets or- Sides of the wheel; by which means the Steam was thrown into the buckets, and set je whee) in wotion. I wished to have bought the machine, not from conpsidering it.in.its then Shape of much utility, but way of conveying the principle to this country, in hopes of ing uselul, but 1 found it was the only one the person

had by bun; and be Said they were.made up the country, and he cowid get me one in two or three months,. but as I was ] ng that country for England a few days afterwards, it of

COULSE prevented my ordering it... Should any thing 1 have | the Smallest utility to my vative country, 1 Shall ratifed, and Should it ſail of proyipg 59,| hops
