Thomas Willson, or Hog Bay (K.I.), wrote in June, 1900, tor 

 me, saying that three persons had applied phosphatic manures i.u 

 1899 to small areas, and speak highly of its effect, so that now 

 considerable quantities are being used. Mr. Dorward, of Port 

 Lincoln (20 in.), used 2 cwt. of kainit for Scotch malting barley, 

 and reaped 25 bushels, or from 6 to 8 bushels more than without 

 it. Mr. J. Brock, of Tanunda (21.56 in.), used 3 cwt. of Peruvian 

 guano per acre at 13 per ton, which resulted in 33 bushels 44 lb., 

 against 8J bushels of poor quality from unmanured land. He had 

 still better results from phosphatic manures at 4/1 0/ per ton. 

 Other guano gave him 38 bushels 48 lb. per acre, against 18 bushels 

 on land not so treated. Mr. R. Puckridge, of Warrow (under 20 

 in. ?) showed splendid sample of Cape, Chevalier, Duckbill, and 

 Scotch malting barley, averaging 24 bushels. 



The average estimated yield on 5,693 acres of barley in 1898/9 

 was in Tasmania 32.36 bushels per acre ; in 1899-0, on 7,606 acres, 

 only 18.76 bushels in consequence of the dry season. 



In conclusion, I may state that the average yield of 17 

 varieties of two-rowed and 19 of six-rowed barley grown on 16 

 farms in British Columbia was 52 J bushels per acre, and the average- 

 weight 57 lb. per bushel; but what fertilisers had been used "is 

 not stated. 



MAIZE. 



The Adelaide Sewage Farm records from 25 to 30 tons of green 

 feed per acre, but although somewhat neglected in South Australia, it 

 gives very good returns in the more north-easterly parts of Aus- 

 tralia. Commercial fertilisers are sometimes used there; but T 

 must fall back chiefly on the experiments made at Hawkesbury 

 Agricultural College (N.S.W.), the United States, and Germany. 

 Those made by the Horticultural Society of North Carolina are re- 

 corded in the form of photographs, without giving actual results 

 as to the crops. A normal manuring with potash, phosphoric 

 acid, and nitrogen increased the crop manifold over unmanured 

 plots, and where lime was added, still more. Green manuring in 

 place of nitrogenous manure was less successful. Where a double 

 quantity of phosphoric acid was given to all others normal +he 

 result was very good ; but where potash was doubled, and the other 

 manures normal, the crop of cobs was much less. Where the 

 nitrogen was doubled the crop was better than from all other plots, 

 except where potash, phosphoric acid, and nitrogen were applied 

 in three times the normal doses. In the last case, however, it i? 

 doubtful whether such quantities of commercial manures gave a 

 payable result. The normal quantity of the manures used were 

 50 lb. of potash, 50 lb. of phosphoric acid, 20 lb. of nitrogen, 2.000 

 lb. of slaked lime ; and for green manuring, cow peas. This would 

 require per acre about 99 lb. of muriate of potash, or 103 lb. of 

 sulphate of potash, 325 lb. of superphosphate or Thomas phosphate, 

 and 125 lb. of nitrate of soda. Professor Wagner manured 

 maize in pots with phosphoric acid and potash, and had
