Vermont grasses and clovers, L. R. Jones ( Vertnont Sta. Bui. 94, PT>- 139-184, 

 figs. 32). — A general description is given of grasses and grass-like plants, together 

 with economic notes on a number of species occurring in Vermont. The relative value 

 of hay, pasture, aud lawn grasses of the different species is discussed, and the clovers 

 and their allied plants are treated in a similar manner. Directions are given for 

 the cultivation of the grasses and clovers, and a chapter is devoted to the impurities 

 which are found in grass and clover seeds. 



Economic notes on some of the g-rasses of southwest Missouri, S. A. 

 HoovKK [Mixsoiiri State lid. A(jt: Rpt. 1902, pp. 449-456). — The results of a study of 

 grasses aud forage plants in four counties in the southwest part of the State are given. 

 A numlier of cultivated and wild grasses are described and their relative value for 

 hay and pasture indicated. 



Kentucky forag'e plants, H. Garman and A. I\I. Petek {Kentucky Sta. Bid. 98, 

 pp. 61, pis. 16) . — In addition to other matter this bulletin discusses the appropriation 

 of free nitrogen by leguminous plants, together with methods of soil inoculation. A 

 list of Kentucky Leguminosfe is given with brief descriptive notes, l)ut the most 

 important ones, including the soy bean, alfalfa, sainfoin, velvet bean, serradella, 

 cowpea, and the principal species of clover are considered more in detail. Notes 

 on 11 varieties of cowpeas grown on plats at the station in 1901 are presented. In 

 addition the results of plat experiments with 22 species of grasses in 1900-1901 are 

 briefly given. The results of an experiment with blue grass seed gathered on dif- 

 ferent dates indicated that this seed should l)e harvested from about June 12 to 

 June 20. One hundred and eight analyses of forage plants from the plat experi- 

 ments are reported in a tal)le. 



Kentucky blue grass seed, A. J. Pieteks and E. Bkown {U.S. Ikpt. Ayr., Bamin, 

 of Plant hidustry Bid. 19, pp. 19, pis. 6, figs. 3). — This bulletin describes the produc- 

 tion of Kentucky blue-grass seed and gives an account of methods of harvesting, 

 curing, and cleaning the same. The industry is confined to areas in Kentucky where 

 much the greater i)ortion is produced and to localities in southern Iowa and northern 

 Missouri. 



A study of the effect of curing on the vitality of the seed was made and the results 

 of germination tests of samples of seed taken at different stages of the curing process 

 are reported. The following conclusions are drawn from the results: " Green seed 

 of Kentucky l)lue grass when put in ricks will ferment and reach a temperature of 

 130 t(j 140° F. in less than 16 hours. A temperature of 1.30 to 140° F. for 16 hours 

 or less will greatly damage if not entirely destroy the \'itality of the seed. Under 

 the present methods of handling green seed it must be stirred at short intervals. 

 The seed must not be stripped until mature, as it is much harder to prevent fermen- 

 tation in the immature seed. Seed should always be put in small ricks, not over 18 

 in. high. Seed can be cured to better advantage undercover in bad weather and 

 outdoors in clear weather." The authors believe artificial curing feasible and rec- 

 ommend that tests be made to demonstrate the practicability of this method. 



The use of corn fertilizers on meadows, E. Zacharewicz {Prog. Ayr. ct Vit. 

 {Ed. VEsl), 23 {1902), Nos. 2, pp. 40-46; 3, ]>p. 83-88).— The subject of fertilizing 

 meadows is considered at some length and the results of cooperative experiments in 

 this connection are reported. It was found that commercial fertilizers were more 

 profitably used on meadows than barnyard manure. Fertilizer formulas for differ- 

 ent kinds of meadows are given. 



The time of applying potash salts on moorland meadows, B. Tacke {Landw. 

 Wch)d>l. S<Mesvng- Hoist ein, 52 {1902), No. 5, pp. 69-71). — The experiments here 

 described led to the conclusion that when there is danger of flooding, potash salts
