when nitrogen was added. Among tbo complete applications the one consisting 

 of 320 lbs. of nitrate of soda, SO lbs. of muriate of potash, and 320 lbs. of acid 

 phosphate per acre gave better returns than the applications in which other 

 proportions of nitrogen and phosphorus were used. 



The seasonal influences on the yield were observed and are discussed. During 

 the favorable seasons the total yield, and also the apparent increase due to fer- 

 tilizers, was greater than in the unfavorable season of 1905. When the fer- 

 tilizing materials were added singly the resulting percentage increase grad- 

 ually decreased with but one exception. When the ferilizers were added in 

 combinations of two this tendency was less marked, while the complete fer- 

 tilizers showed very strongly the opi>osite tendency. A computation (if the net 

 gains for the 3 years shows that 20 tons of barnyard manure gave $84.59 profit 

 per acre. 10 tons of manure $50.02. and 320 lbs. each of nitrate of soda and acid 

 phosphate with SO lbs. of muriate of potash $40.70. 



Lime on this Dunkirk clay loam soil did not give an increased yield of tim- 

 othy hay. Suggestions on fertilizing for timothy, based on the results of this 

 work, conclude the bulletin. 



Experimental field work in 1906-7, E. T. Drake {Tictorian Yearbook, 28 

 (1907-S). i>i). 605-609). — Brief notes on Aarious lines of work are given. In 

 variety tests with wheats Federation ranked first w-ith 43 bu. per acre, fol- 

 lowed in decreasing order of yield by Dart Imperial, Australian Talavera, Jade, 

 Sussex. Silver King, Tarragon. White Tuscan. Frampton. and Marshall No. 3. 

 In two localities ordinary bare fallow produced more wheat per acre than sub- 

 soil fallow, but in one region subsoil fallow exceeded the yield on bare fallow 

 each year. 



Report of the fourth annual meeting' of the Canadian Seed Grow^ers' As- 

 sociation (Canud. Seed droicers' Assoe. Reijt., Jf, (1908), pp. 100). — The minutes 

 of the fourth annual meeting of the organization are reported and the papers 

 and addresses presented and reproduced. The subjects under discussion related 

 mainly to plant improvement for various puri)oses.

American varieties of beans, C. D. Jarvis {'Sew York Cornell St a. Bui. 260, 

 j)p. 153-255, pis. 17). — This bulletin contains a key together with complete de- 

 scriptions, synonyms, and historical and comparative notes on the varieties of 

 beans now grown in America. The key is based upon the form and color of the 

 fresh seed, thus differing from the metht)d of determining varieties advocated 

 by W. W. Tracy, jr., who used plant, pod, and seed characters (E. S. R., 19, 

 p. 539). Since seed varies somewhat in size and coloring according to the 

 locality, this key is held to be more applicable to northern-grown seed. The 

 varieties of each species {Phaseolns vulgaris, P. lunatus, and P. multiflorus) 

 are grouped as dwarf and climbing forms, and these are subdivided into green- 

 podded and wax-podded varieties, the individual varieties of the various sub- 

 classes being treated in alphabetical order. 



The descriptions are accompanied by a series of plates, showing the side and 

 ventral views of ripe seed, cross sections (jf snap pods, and side views of the 

 snap and green-shell pods. An attemi)t has been made to simplify and correct 

 the now confused nomenclature. The work is based upon field studies made by 

 the author at Cornell in 1905, at the Connecticut Storrs Station in 1906 antl 

 1907, and cooperative studies with a commercial seed firm at Le Roy, N. Y., 

 and with the Bureau of Plant Industry of this Department, as well as upon an 

 investigation of previous experimental work along this line. The bulletin is
