one of the finest sand \vc could procure, making altogether 

 two feet in thickness of sijjcious substances. The water, 

 which is received into No. 1, passes through the leaden pipe 

 into No. 2, and filtrates by ascent through the strata of 

 sand and gravel, the space below the level of the oak floor 

 in both wells, acting as a qespoolj receives all sediment. 

 The pump is of course affixed in the filtering well. Both 

 wells arc covered up, but plenty of air is admitted to them, 

 through apertures made for thh purpose. 

 Advantages of You will immediately perceive, that the merit of jtjiis plan 

 * P au " consists altogether in the filtration by ascent, with a compe- 



tent space under the apparatus. The interstices of the sand 

 are thus never clogged, and its power is preserved unim- 

 paired for an indefinite period. The well fully answers its 

 intended purpose, and tjie water is altogether excellent. I 

 have been tempted to submit this statement to you from a 

 persuasion, that there are few houses, which may not be 

 made in this maimer to supply excellent water in sufficient 

 quantity for domestic consumption; and that situations 

 abound, where the filtrating well may be resorted to with 

 equal comfort and advantage.

Your obedient humble Servant,
