consists of fotton-seed meal, is most effective wiieii liedded on from 7 to K! days 

 in advance of planting. 



Cross planting cotton with corn was not fonnd protitalile. It was aiso shown 

 that the use of sound cotton seed directly as a fertilizer or a fertilizer ingredient 

 is a very unwise practice. 



Applications of 4(M>. ,S(M), and 1.200 lbs. of a fertilizer consisting of 1,000 lbs. of 

 17 per cent acid phosphate, 498 lbs. cotton-seed meal, and 74 lbs. muriate of 

 potash v.-ere compared. The plats receiving 400 lbs. at a cost of $4 produced 

 281 lbs. of seed cotton more per acre than the unfertilized plats. The use of 800 

 lbs. increased the yield over the check' plats by 430 lbs., and the use of 1,200 

 lbs. showed an increase of 588 lbs. of seed cotton. Cotton hulls as a fertilizer 

 did not prove profitable. 



In a condensed review of the results of 17 years of cotton culture it is pointed 

 out that plowing from 6 to 8 in. deep and thoroughly harrowing the land is more 

 effective than deeper but less careful breaking and fining of the soil. Subsoiling 

 has not been fouiad advisable on the upland soils of middle Georgia. The 

 results of the variety tests seem to favor a variety with large bolls, large seed, 

 high percentage of lint, medium earliuess, and persistent fruiting ca])acity. 

 On land capable of yielding | to li bales per acre the rows are recommended 

 to be oj to 4 ft. wide, with the plants 12 to 18 in. apart in the frills. 



With regard to commercial fertilizers it is stated that these should l)e ajiplied 

 and bedded on not less than a week before planting, and that it does not pay 

 to divide the amount into 2 or more applications, although nitrate of soda may 

 sometimes l)e ai^plied with profit a month or more after planting. As a general 

 rule shallow cultivation once a week and once in a row is advised. The rotation 

 of crops laid down consists of small grain followed by cowpeas the first year, 

 cotton followed by rye or vetch the second year, and corn and peas the third 

 year. 



An interesting cross between a variety of eninier and spelt, P. H. Stoll 

 (Dent. Landw. Presuc. S.'i (1907), No. 13, p. 100. fif/s. 2). — Reciprocal crosses 

 were made between a hairy, bearded winter emmer and Stoll brown winter 

 spelt, itself a cross betwgen Main standup wheat and red winter spelt. The 

 use of emmer as the male parent resulted in 5 poorly developed kernels which 

 failed to germinate, while the use of spelt as the male parent gave a single 

 grain which germinated vigorously and survived the winter in the open. The 

 plant from this seed showed the beardless character of the spelt and the 

 hairiness of the emmer. In form of spike and strength of stem it resembled 

 spelt. The author considers beardless heads and hairy glumes as dominant 

 and bearded heads and smooth glumes as recessive characters. The second 

 generation was characterized by uniltiplicity of forms. 



Flax culture, W. L. Marcy (U. H. Dept. Ai/r.. Fanners' Bill. 21 'i, pp. 36. figs. 

 11). — This bulletin is an extract from a rei)ort on this subject published by 

 the North Dakota Station as Bulletin 71, which has already been noted (E. S. 

 R., IS. p. o:!2). 



Flax experiments, 1905 (Dept. Agr. and Tech. Iiisti: Ireland Jour., 7 

 (1907), No. 2, pp. 250-2()8). — The results of • this year's fertilizer experiments 

 confirm the conclusion of previous years that a potassic manure either in the 

 form of kainit, muriate of potash, or sulphate of potash is generally profitable 

 when applied to the flax crop, and that such treatment effectually prevents yel- 

 lowing. A comparison of seed from different sources showed the net returns 

 per acre from home-saved seed to be inferior to Dutch seed and Kostroma s?ed 

 imported from Russia, but better than those yielded by the Belfast brand of 

 Riga seed. 



As in previous years scutching tests were made to determine the comparative
