Uie elements and accessories of mateiia}, and, consequently, of 

 mental refinement, l)ave been neglecteil. Such are the enoi-3 

 of the past; but tliere are now, however, indubitable proofs of 

 the movements of civilization onward and upward." 



Mr. Carter, of Brooklyn. — The cheapest phtn for bringing water 

 under ground considerable distances is by using water cnneni. 

 Make a ditch a foot deep and wide enough ibr a maa to work in 

 It J then make another,on1y four or five inches wide and six deep; 

 put into the latter some prepared cemt^nt, place on it a pole as 

 large as the tube you desire, put cemt^nt on top of tliat, work 

 the cement and twist the pole until you have made it right, then 

 draw out the pole. Before the cement sets, take a fork and piick 

 holes enough in your cement pipe to let water in ; as ?oon as th& 

 pipe is set, cover up. Tliis operation will not cost more ihan 

 two cents a foot. Hollow bricks have been made with advantage 

 for buildings, they keeping always dry, and can be used lor 

 draining. 



Dr. Antisell. — Will not long cement drains, such, as yon des 

 cribe,be liable to break from contraction, upheaval of ground, ttc.1 

 Would it not be best to make it in short sections^ 



Mr. Carter. — It should be laid below frost. 



General Chandler. — I take occasion and deem it proper to state, 

 for the information of all whom it may concern, that a company 

 is organized on Staten Island for making drain tiles. The agent 

 of the Company, Mr. Dunning, has an office at No. 1 Bonil-street, 

 111 this city. The tiles they make are about one foot long and 

 the cost about one cent each. 



Mr. Carter. — Did not like the sole tile as well as that of an 

 oval form. If I used the sole tile I should set it side upfcrmost. 



Dr. Antisell. — On heavy lands, wliere the quantity of wafer 13 

 large, the flat solid tiles appear to act efficaciously, bfcaiisr they 

 have a greater purchase on the ground an.d are not, therefore, 

 lialde to shift; foi the mere flow of water in drains of large di- 

 mensions, the form is not so material, but in small ones it is. 

 The London sewers are of oval form.
