samples of marsh, creek, and tidal deposits; 1 sample of marl; 2 samples of lobster 

 refuse (bodies and tails) ; 1 of limekiln ashes; 1 of purslane; 1 of a fraudulent mixture

On the fertilizing value of olive cake (L'Enyrais, 14 ( 1899), No. 7, p. 159). — Analy- 

 ses are given which show 0.75 to 0.77 per cent of nitrogen, 0.17 to 0.20 per cent of 

 phosphoric acid, anil 0.13 to 0.45 per cent of potash. 



Inspections for 1897, C. D. Woods (Maine Sta. Bpt. 1897, pp. 52-60).— This is a 

 brief summary of the work done during the year in the inspection of fertilizers and 

 feeding stuffs, with brief reference to the testing of seeds and of chemical glassware 

 used in creameries. 



The fertilizer law of South Australia, W. L. Summers {Jour. Ayr. and Ind., 

 South Australia, 2 (1899), No. 6, pp. 499, 500).— An abstract. 



Tabulated analyses of commercial fertilizers, T. J. Edge and W. Frear (Penn- 

 sylvania Dipt. Ayr. Bpt. 1897, pp. 797-836). — A reprint of Bui. 33, Pennsylvania Dept. 

 Agr. (E. S. E., 9, pp. 825). 



Fertilizer experiments -with steamed bone meal, B. Schuxze (Jahrb. Ayr. ('hem. 

 Vers. Star. Breslau, 1896; abs. in Centbl. Ayr. Chan., 28 (1899), No. 2, pp. 81-85).— 

 From the results of experiments with winter wheat, potatoes, and sugar beets on 

 loamy and clayey soils rich in humus the author concludes that bone meal is about 

 as effective as superphosphate. 



Is intensive manuring profitable at present prices for crops? I'. Wagner 

 (Ztsclu. Landw. T'er. Ressen, 1SDS, Xo. 14, p. 125; abs. in Centbl. Ayr. Chem.,28 (1899), 

 No. . , pp. S5-S9).— The results of numerous experiments are. cited to show that under 

 the conditions of these experiments this question should be answered in the 

 affirmative. 



FIELD CROPS. 



Experiments with field crops, W. Saunders (Canada Expt. Forms 

 Bpt, 1897, pp. 5-60, fig, l,pls. 2). — The experiments in 1897 consisted "of 

 variety, fertilizer, and culture tests with field and forage crops. The 

 results of vitality tests of "rain and other seeds, and the amount of 

 seed distributed in 1897 are reported in tables. The average results of 

 the variety tests obtained on all the experimental farms has been pre- 

 viously reported (E. S. R., 9, p. 82G). 



Experiments were begun to ascertain the value of rolling and har- 

 rowing land sown with clover, and of sowing different quantities of 

 clover per acre with barley. Harrowing only after sowing without roll- 

 ing gave the best yield. However, the plat not rolled or harrowed 

 after sowing yielded but 1 bu. per acre less. The experiments showed 

 that clover can be grown with grain without lessening the yield. About 

 10 lbs. of clover seed per acre was used in most cases. The largest 

 weight of clover leaves, stems, and roots, 8 tons 505 lbs. per acre, was 

 produced on 2 plats, one sown with oats and 10 lbs. of mammoth red 

 clover per acre, and the other with barley and 10 lbs. of common red 

 clover per acre. The weight was determined on October 20. 



Horse beans, soy beans, sunflowers, buckwheat, flax, and awnless 

 brome grass were grown experimentally. Short notes on each crop and 

 the yields produced are given. The results of fertilizer experiments 

 carried on for a number of years with 19 applications of various fertil- 

 izers, used singly and in different combinations, are reported in tables. 

 The crops grown in connection with these tests were wheat, barley,
