1130 APPENDIX A. 



sandy or gravelly soil, it should be puddled or covered with clay to 

 prevent the leaking and escape of the liquid manure. The floors of 

 the stables may be so made as to permit the urine to fall on to the 

 properly prepared bed of turf under them, where it would be re- 

 tained till remove'd ; or it should be led off by troughs into the yard 

 or to a muck heap. 



Superphosphate of Lime. — Take a large tub or barrel, and put 

 into it 100 lbs. water ; add, very slowly and cautiously, 43 lbs. of 

 pure sulphuric acid ; you must be very careful while handling thin 

 article not to let it touch your skin or clothing, as it will instantly 

 blacken the skin, and destroy the clot-hing, wherever [t comes in 

 contact ; and, when mixed With water, it engenders a very intense 

 heat. Into this mixture throw 100 lbs. weight of bones, no matter 

 how old or useless they may be. The sulphuric acid instantly at- 

 tacks and enters into combination with the bones, reducing them to 

 a pasty consistency, and completely dissolving them. Keep under 

 cover, and turn them over occasionally, while the process is going 

 on ; and, when completed, dump out the whole contents on to the 

 barn floor or a platform of boards, and thoroughly work into the 

 mass four times its bulk of dry bog earth or dry road dust j mix and 

 pulverize completely with a wooden shovel. The bog earth acts as 

 an absorbent,, or drier, retaining the fertilizing properties of the 

 compound, and rendering it easy of uniform distribution. If whole 

 bones are used, it will take six or eight weeks to dissolve them ; if 

 they are broken with an axe, they will dissolve in about three 

 weeks; if they are ground in a bone-mill, four days will be suffi- 

 cient. This manure is the most powerfuL fertilizer in existence ; 

 and, when made by these directions, it is the cheapest, as one ton is 

 equal to thirty-two tons of barn-yard manure. For toprdressing for 

 grass lands, use 300 lbs. per acre ; for corn, potatoes, beans, turnips, 

 etc., apply 450 lbs. per acre in the drill, mixing with the soil ; for 

 wheat, rye, oats, or barley, 400 lbs. per acre, harrowing in with the 

 seed ; for buckwheat, 300 lbs. per acre. 



Home-made Guano of Unequalled Excellence. — Save all your 

 fowl manure from sun and rain. To prepare it for use, spread a 

 layer of dry swamp muck (the blacker it is the better) on your barn 

 floor, and dump on to it the whole of your fowl manure ; beat it into 

 fine powder with the back of* your spade ; this done, add hard-wood 

 ashes and plaster of Paris, so that the compound shall be composed 

 of the following proportions : Dried muck, three bushels ; fowl 

 manure, two bushels ; ashes one bushel ; plaster, one and one-half
