found profitable, but heavy <ire8!<ing of kainit decreased the yield. The u.se of 

 kainit on all farms lowered the percentage of dry matter in the tuberi?, the average 

 reduction amounting to 2.38 per cent. Barnyard manure for potatoes is recom- 

 mended when the crop follows a fallow, but when sui'h is not the case commercial 

 fertilizers are considered best.

 station in 1900 (.S'ac//.s. Landir. ZtscJir., 49 {1901), Xo. 9, pp. 161-166) .—The results 

 in yield of the tubers and starch of 18 varieties of potatoes are recorded. 



New varieties of potatoes, A. Dubois {Jour. Agr. Prat., 1901, I, No. 11, pp. 343, 

 344). — A description of several new varieties of potatoes is given. 



Producing a new potato by grafting, J. R. Lawrexce {Amer. Agr. {mid. ed.), 

 67 {1901), Xu. 16, ]). 068). — The author claims to have produced a new variety by 

 grafting the eye of Scotch Rose on a tuber of Maule Commercial. 



Fertilizer experiments, Kuhxert {L'lndw. Wchnhl. Schleswig-Holiitein, -51 {1901), 

 Xo. 11, pp. 166-168).— A. report on cooperative fertilizer experiments with beets and 

 potatoes, the results of which led to the conclusion that lime must be used on marsh 

 soils in conjunction with commercial fertilizers if these are to be fully effective. 



Culture of ramie and other fiber plants in China, M. Schanz {Tropenpjianzer, 

 5 {1901), Xo. S, pp. 126-1.36). — Twelve of the most important Chinese fiber plants 

 are descril)ed, and the culture of ramie, as it is carried on in China, together with 

 a description of the process of decortication and the methods of exportation, is 

 disrusscd. 



Progress in the beet-sugar industry in the United States in 1900 (f. S. 

 Dept. Agr. Rpt. 69, pp. 178). — This is the customary annual report on the progress of 

 the beet-sugar industry in the. United States, and is similar in character to the reports 

 previously noted (E. S. R., 12, p. 742). 



Report of the special agent, C. F. Saylor (pp. 5-122). — This report discusses in a gen- 

 eral way the consumption of sugar in the United States, the forces which are edu- 

 cating the people in regard to the l)eet-sugar industrj', American-made machinery 

 and implements, bounties and other methods of promoting the industry, distribution 

 and production of seed, the utilization of wastes and liy-products of factories, and the 

 cultivation and fertilization of the soil. The crop conditions and factory operations 

 during the year are noted in detail for each State. Factories are now in operation Ln 

 California, Colorado, Illinois, ^Michigan, Minnesota, Nebraska, New Mexico, New York, 

 Ohio, C)regon, Utah, and Washington. New factory enterprises are reported from 

 Colorado, Indiana, Iowa, Michigan, North Dakota, Oregon, Utah, South Dakota, and 

 Wisconsin. Short discussions by different investigators and beet-sugar manufacturers 

 on insect enemies and di.^eases affecting the sugar beet are presented, and reports 

 from directors of experiment stations regarding culture, sugar content, and purity of 

 Vjeets grown at the stations and throughout the corresi)onding States are reproduced. 

 These data have largely been published in the station bulletins. 



Report of the clieniisi, If. IT. llVAy/ (pp. 123-171 ).— This report presents the results 

 of analysis of sugar beets grown on the experimental grounds of the Department of 

 Agriculture and on trial plats of individual growers throughout the country, to whom 

 seed were furnished by the Department. The tal)ulations show the number of sam- 

 ples received from each State and Territory, the variety of each sample, the weight 

 of the beets, their sugar content, tlu; purity coefficients of the juice, and other data 

 of interest in connection with the i)roduction of beets for the manufacture of sugar. 

 The average results ior each year since 1897 are summarized and discussed by States.
