 SIR, 



Introduction. A AM fenfible that the little engine, a drawing of which ac- 

 companies this letter, can lay no great claim to novelty in its 

 principle; neverthelefs it isrefpedfully fubmitted to the con-

 of conftruclion, may render it worthy of their attention, with 

 a view to its being more generally known and ufed in fimilar 

 cafes. 

 Height of Irton- Irton-Hall, the feat of E. L. Irton, Efq. is fituated on an 

 Hall 6o feet a- afcent of fixty or fixty-one feet perpendicular height; at the 

 * foot of which, at the diftance of about 140 yards from the 

 offices, runs a fmall ftream of water. The object was toraife 

 this to the houfe for domeftie purpofes. 



To this end a dam was made at a ihort diftance above> fo 

 as to caufe a fall of about four feet; and the water was brought 

 by a wooden trough, into which was inferted a piece of two- 

 inch leaden pipe, a part of which is feen at A, plate 2.
