while the uninanured land gave half a ton. At Port Elliot 3 cwt. 

 of this guano gave 25 per cent, more hay than unmanured, and 2 

 cwt. of bone phosphate to Algerian oats gave 50 per cent, more hay 

 from the manured crop, on black soil in Teatree Gully (about 25 in.) 

 1 ton of hay per acre. Mr. Isaacson, of Auburn (24.40) had Gcwt.more 

 hay per acre where he had manured with Thomas phosphate. Of 

 course, the above poor results were in an exceedingly dry season, 

 but, irrespective of the hay obtained from land manured with 

 phosphates and potash, containing much more albumenoids, actually 

 up to 11 per cent., against 6 per cent., and to 0.6 per cent, of 

 phosphoric acid, we are all well aware that hay or grass grown on 

 dry land, and in dry seasons, is far preferable to that grown even ID 

 our South-East with a greater rainfall. The proportionate feed- 

 ing value is at least 104 to 100. 



CLOVER. 



M. de Vuyst declares his experiences made in fruit- 

 ful clayey soils to Be that potash has there been profitable for 

 clovers, and recommends the application of 480 Ib. of kainit per 

 acre. Mr. Hy. Thompson, M.R.C.V.S., Secretary of the Aspatri? 

 Agricultural Co-Operative Society, which supplies to its members 

 large quantities of commercial manures, says: "Kainit is invaluable 

 for clover. The best results are got where not less than 5 cwt. 

 per acre are applied at the back-end of the year." Professor Dr. P. 

 Wagner says in Heft. III. of his "Manurial Questions" : "In the 

 same soil, where cereals grew but miserably unless manured with 

 nitrogen, and where manuring with potash and phosphoric acid 

 remained without effect, red clover was indifferent to nitrate of 

 soda; but manuring with potash and phosphoric acid brought 

 them to luxuriant development/' He admits that on the very 

 poorest soils a small quantity of nitrate of soda may after all be 

 advisable. Red clover sown without manure in pots gave in 

 three cuts 33 g., 49 g., and 29 g., against 94 g., 98 g., and 69 g. 

 where potash and phosphoric acid was given, I give now a few ex- 

 periments made in France, which might be followed here, adding 

 potash. M. Lefeuvre, at Dominelais, harvested with 32,000 Ib. 

 of dung, in two cuts, 3,688 Ib. of clover per acre; with 1,600 Ib 

 of Thomas phosphate, 7,064 Ib. Abbe M. Quillet, of Malans, ob- 

 tained without dung only one cut; but he had with 80 Ib. of 

 Thomas phosphate two equally good cuts of 2,664 Ib. each, or an 

 excess over the one cut of 3,328 Ib. M. Bessirard, of Argentan. 

 had, with 320 Ib. per acre of Thomas phosphate, 1,680 Ib. more 

 hay, and with 480 Ib. of Thomas phosphate 3,120 Ib. more than 

 without any manure. Whether the soil for these experiments alsc 

 obtained potash or was rich in potash, I cannot say. At all events 

 potash would have increased the crop. In a favorable soil plants 

 two months old should have their roots 2 ft. cleep, at five months to 

 5 ft. and more. 



The Agricultural Union of Spelle, in Hanover, had three expe- 

 rimental plots sown with clover without any cereal. No. 1, un-
