 Chem. Inch, 18 (1S99), Xo. 3, pp. 213-224, figs. 4).— A. brief history of these deposits. 



Analyses of bat guano, F. Watts (Jour. Jamaica Agr. Soc., 3 (1S99), Xo. 3, p. 

 153). — Analyses of samples of medium and rich quality, representative of deposits 

 on the island of Jamaica.

 agriculture, D. HOOPER (Agr. Ledger, 189S, Xo. 20 (Agr. ser., Xo. 23), pp. 19). — These 

 nodules, which are found scattered over the surface or distributed through the soil 

 in more or less abundance over a considerable area in this district, showed on 

 analysis 53 to GO per cent of tricalcium phosphate, I to 8 per cent of oxid of iron 

 and alumina, and 1? to 23 per cent of calcium carbonate.

 Xo. 8, pp. 179-181). — A discussion, based largely upon the work of Ullmann, of the 

 fertilizing value of the free lime of Thomas slag and the gypsum of superphosphates.

 Seelhorst (Jour. Landw., 47 (1899), Xo. 1, pp. 91-94). — An explanation of some of 

 the details of the experiments reported in the article noted above (p. 1033).

FIELD CROPS. 



Results obtained in 1898 from trial plats of grain, fodder corn, 

 and roots, W. Saunders (Canada Gent. Eotypt. Farm Bui. 32, pp. 47,

 viously reported (E. S. R., 9, p. 82G). The general plan of the experi- 

 ments remained unchanged. The results are given in tabular form. 



Taking the average results obtained on all the experimental farms

 mentioned in their order, were as follows :

 American Beauty, California Prolific Black, Abundance, White Schonen, Mennouite, 

 and Golden Beauty. Two-rowed barley. — Beaver, Dunham, Danish Chevalier, Newton, 

 French Chevalier, and Prize Prolific. Six-rowed barley. — Pioneer, Stella, Odessa, 

 Mensury, Oderbruch, and Trooper. Spring wheat. — Wellman Fife, Monarch, White 

 Connell, Goose. White Fife, Red Fife, Preston, Progress, Percy, Rio Grande, Stanley, 

 and Emporium. Peas. — Perth, Pride, Elephant Blue, King, Harrison Glory, Trilby, 

 Vincent, Early Britain, Pictou, New Potter, German White, and Bruce. Corn. — Red 

 Cob Ensilage, Giant Prolific Ensilage, Thoroughbred White Flint, Early Mastodon, 

 Champion White Pearl, and Cloud Early Yellow. Turnips. — Purple-top Swede, 

 Jumbo, Giant King, Sutton Champion, Hall Westbury, and Perfection. Swede.

 mediate, Improved Short White, Half Long White, White Belgian, Green Top White
