The above material has been successfully introduced as litter %ihorses in Ohio, instead ot straw, and may be profitably employed for this purpose when thelatter article is dear. The "Ohio Cultivator ."contains the following remarks upon the subject : " Several bushels of dry saw-dust are thrown into the stall, upon which the horse,,s nds during the night. In the morning it will "he found that about a bushel has to be removed—one-half of which is manure and one-half saw-dust, so well saturated as to contain a large portion ot ammonia, performing the double office of absorbent" and purifier ; thus the air of the stable is kept pure, and the ammonia saved for the compost heap. This compost Mr. Blake has applied to his stiff clay land, and reports that it operates like yeast, making the ground very light and mellow. In the morning, that portion of the bedding which remains dry, is shoved up under the manger, to serve for another night. Another advantage from this material for bedding is that a horse which lies upon it is much easier cleaned off than one which lies oa straw ; the saw-dust entering among the hair brings away the secretions, when the curry comb and brush are applied, leaving a bright lively coat. In warm weather it has another great advantage, that of being much cooler than straw, so that a tired and heated horse can sleep pleasantly, without incitements to feverish restlessness. The establishment ot steam mills in all parts of the country, renders the material easy of access to almost every neighborhood, and we doubt not. when its virtues are better known, it will be generally applied to stable use, as a means of comfort to the horse, and also of turning an otherwise useless article into profitable account." A diamond of beautiful form and the first water, accompanied by a fine sapphire, has been found in Australia. Mr. Avery, whose improvement in joining stones was noticed last week, resides in Norwich, Conn., and not Stonington, as erroneously mentioned.
