1869.] Manufactures Reviewed. 479 The foundation of the building is con- stantly in water, about 19| inches below the level of the ground floor. The entire horizontal surface of the external and internal walls was covered, at the level of the internal ground floor, with a laj^er of Se3^ssel Asphalte, half an inch thick, over which sand was spread. Since the above date, no trace of damp has shown itself round the walls of the lower story, which are for the most part painted in oil of a grey stone color. It is well known that the least moisture produces round spots, darker or lighter, on walls so painted ; 3 T et the pavement of the floor, resting on the soil itself, is only about 2J inches above the external surface of the wall, and only 19^ inches, at the utmost, above that of the sheet of water. The L^yer of Asphalte having been broken and removed, for the pur- pose of inserting the sills of two doors, spots indicating the presence of damp have been since remarked, at the base of the door posts." Ann Street Iron Works, Belfast, Ireland. — We are favored with a beau- tifully illustrated quarto pamphlet of Patent Stable Fittings, Patent Iron Cow-House Fittings, and general work executed at the above establishment of Musgrave Brothers. The number of merit-medals bestowed from time to time on these gentlemen, for the exceed- ing excellence of many of their produc- tions, is a proof that their claim on us for notice is unquestionable. On this side of the Atlantic, we have not hith- erto bestowed all that attention on the sanitary housing of our horses, we ought ; partly because the higher bloods were not so much cared for, as that class of the equine race is in the old country ; and partly, and perhaps chiefly, because our citizens were too engrossed in the making of monej', to bestow attention on the rapidest mode of spending it. However, we have been altogether be- hind the times, in the comforts of the Stable ; and would therefore urge the necessity for a thorough revision of our system, which is, we trust, not yet too stable to be reformed. HOME. American Ventilation Company. — When the late Professor Espy patented his ventilator, many years ago, we thought that the " ken " of science could no farther go. But, here is Griffith's Patent Archimedean Screw Ventilator and Smoke Conductor, which is far more effective, more durable and less liable to go out of order. This simple, yet com- plete Ventilator, consists of an Archimedean Screw, suspended within a cylin- der, centered upon an imperishable substance, moving without noise, and surmounted by a rotary head, which is so delicately hung, that the least breath of air will cause it to revolve. The screw within the cylinder, revolving with almost in- conceivable rapidity, acts as a pump, exhausting the air from the flue, thereby creating a tendency to vacuum, which must be filled from below. This simple explanation will show to all that in a chimney or ventilation flue, topped by one of these ventilators, a draught is a necessary effect. Permanent Liquid Glue. — A good fluid glue, reacty at all times for instant use, without any preliminary prepara- tion, is one of the most useful articles of stock, with which the workshop of any mechanic can be furnished. To make such a glue, all that is necessary is to melt three pounds of glue in a quart of water ; and then drop in, gradually, a small quantity of nitric acid. When this ingredient is added, the mixture is to be removed from the fire and allowed to cool. Glue so prepared has been kept, in an open bottle, for two years ; and has alwaj-s been found ready for use on the instant, not deteriorated in the least.
