Construction, of cm Ice-House.— Sir, I have lately had an ice-house 

 erected, and, as I think a plan of its construction may be useful to others 

 wishing to build one, I send you a sketch of the section, {fig. 106.) 



a Entrance, about 4 ft. wide inside. i, Lobby. c, Cast-iron door, frame, and plate. 

 d, S|)nnginK line for tlie covering arch. e. Cast-iron bottom, witli holes. 



/, Cistern. g. Drain, 6 in. in diameter. h h h h. Puddle of clay well rammed in. 

 i'. Air trap. k. Steps down to the entrance. 



A drain with a proper trap is better than trusting to the absorption of 

 the water by the adjoining soil, as the latter commonly admits air. The 

 cistern and traps should be well cemented inside, and the puddle round all 

 the external walls should be well rammed in. Cast iron is ultimately 

 cheaper than oak ; as, when the latter decays, which it does very quickly, 

 it is very difficult to get it renewed. The walls are drawn 9 in. thick, but I 

 think 14 in, better. Estimating the walls at 14 in., bricks at 30s. a thou- 

 sand, and the iron at 18s. per cwt., the total cost of such an ice-house 

 would be about Ibl. Yours, &c. —J.S. January 24. 1831. 



Front Elevation of a Conservatory. — Sir, As you solicit designs as well 

 as other communications from your various readers, you will, perhaps, not 

 dislike a few elevations from those among them who are amateur architects.
