results for 5 years show that the yields per acre of medium varieties were 90 cts. 

 j^reater in value than the yields of early varieties, while the yields of the mixtures 

 exceeded those of the medium varieties by $1.34. If the 2 varieties are equally 

 productive from year to year it is considered expedient to mix them. 



The results of ilistance experiments conducted for 4 years are in favor of s])acing 

 plants 12 in. apart in 4-ft. rows. This test had reference only ti) the distance between 

 plants in the row. From a series of experiments the author concludes that on ui)lund 

 middle Ge()r<j;ia soils, capable of yieldinoj 800 to 1,200 lbs. of seed cotton per acre, the 

 rows should not be wider than 36 in. and the plants in the row not over 12 in. apart. 



An unfavorable season and the appearance of rust interfered with the results of a 

 fertilizer test made for the purpose of determining the best proj^ortion of nitrogen in 

 a mixture containing available phosphoric acid and potash in the constant propor- 

 tion (if 4 : 1. As the nitrogen was diminished in the applications the phosphoric acid 

 and jxitash were increased to the extent of making the money value of the applica- 

 tion uniform in all cases. The general application of nitrogen was given in the form 

 of cotton-seed meal, but in each case 15.6 lbs. of nitrate of soda were applied when 

 the seed was jilanted. The experiment was made in duplicate. Where cowpea vines 

 had been turned under ])efore planting to cotton the crop practically escaped injury 

 from rust. In a general way, the results of one experiment indicated that the yield 

 increased quite regularly as the supply of nitrogen was diminished. In the duplicate 

 test lack of moisture interfered with the results. 



In the second fertilizer experiment potash in the form of muriate was successively 

 diminished and the quantity of acid phosphate and cotton-seed meal correspondingly 

 increased so that in all cases the cost of the fertilizer amounted to $4.17 per acre. In 

 this tost the fertilizers were practically witliout effect. 



The weather conditions during the growing season for a series of years are tabu- 

 lated. Fertilizer formulas for various crops on different kinds of soils are given in 

 an ajipendix. 



Cotton culture, J. 8. Newman [Sontli <_'(irn/in<i Sfn. Jlnl. 7o, jip. l->,fifjx. ->). — Popu- 

 lar directions are given for the culture of cotton in South Carolina. 



Peas and the pea -weevil, C. A. Zavitz and W. LocnnEAD {Ontario Agr. Col. and 

 E.ipt. Farm Bui. 126, pp. 32, figs. 9). — This bulletin contains a summarized account 

 of the cultural work with peas at the Ontario Agricultural College, together with the 

 results of experiments in the control of the pea weevil. The pea weevil is described 

 in detail and a map given showing the pre.sent distribution of this insect in Canada. 

 More than 100 varieties of peas have been grown in the experimental grounds at the 

 college during the past 14 years. A table is given showing the character of the vines 

 as regards growth and susceptibility to weevils, yield, etc., of 26 leading varieties for 

 a period of 7 years. 



Some varieties of peas, like New Canadian Beauty, are double in size those of other 

 varieties like Common Golden Vine, and her ce in seeding it has been found neces- 

 sary to vary the amount sown from 2 to 3^ bu. per acre. The time of maturity has 

 varied for 26 varieties from 94 to 101 days and the extremes in length of vines from 

 19 to 52 in. The yields per acre have varied from 23 to 38 bu. The average weight 

 ])er bushel has been 59.4 lbs. for whole peas. Weevilled peas varied in weight from 

 38 to 52 lbs., and usually the smaller the peas the greater amount of injury done by 

 weevils. The Ijest yielding varieties for the whole province, averaging upward of 

 25 l)n. per acre, are the Egyptian INIummy, Chancellor, Prussian Blue, and Striped 

 Wi.st'onsin Blue. Other varieties averaging between 24 and 25 bu. per acre are Early 

 Britain, Canadian Beauty, and Canada Cluster. The reports of experimenters show 

 that with but few exceptions there are no pea weevils north and east of a line drawn 

 from Brockville to Midland. 



Experiments for a numljer of years in selecting large and small seed of the same 

 variety resulted in an average yield of 30.3 bu. of grain and IJ tons of straw per acre
