was fuuud iu 540 .samples of alfalfa; 42 varieties were found in 99 samples of 

 timothy; 31 iu 58 samples of red clover; aud 31 iu 260 samples of oats, and 

 smaller numbers in the remaining IS kinds of seed examined. 



Seed tests made at the station during 1914, M. T. Munn (Xew York State 

 Sta. Bid. 30^ {1015). pp. 27).— This bulletin drives results of analyses of 303 

 official sjimples of seed and 1.155 samples sent in by correspondents in 1914, 

 and discusses the method of analysis and rocpiirements of the seed law and its 

 significauce to New York farmers. 



Of the ofBcial samples 10.9 i^er cent showed violations of the law, these being 

 mainly alsike clover samples contaminated in the field with other crop seeds. 

 However, " the present seed law affords only a partial protection to the pur- 

 chasers of seed, since it does not require a reasonable freedom from dodder or 

 other noxious weeds or from inert matter." 



Analysis of the correspondents' samples "indicate that the number of kinds 

 of weed seeds found in ci'op seeds for sale in this State is increasing." 



Purity of farm seeds in 1914, F. 11. IIai.l (Netc York State Sta. But. 39Jf 

 (I'JJS), popular c(l., pp. If, fill. 1). — A popular edition of tlie above. 



Agricultural seed, G. P. Burns {Vermont Sta. But. 183 {1914), PP- 269- 

 294) ■ — This bulletin gives the text of the A'ermont seed inspection law and 

 shows in tabular form the results of examining 234 official samples and about 

 100 voluntary samples. Alfalfa, alsike clover, corn, millets, red clover, redtop, 

 and timothy seed as sold in Vermont was compared with the I'nited States 

 standard, a large part of the samples other than redtop being equal to or better 

 than the standard. Eighty-live per cent of the seed other than redtop was of 

 standard quality as regards purity and 8S per cent as regards viability. 



Suppression of weeds among pineapples by arsenite of soda spray, F. G. 

 Krauss {Hawaii Sta. Press Bui. 48 {1915), pp. 8, figs. 2.) — This describes meth- 

 ods and apparatus used iu successfully destroying weeds on pineapple planta- 

 tions by the use of arsenite of soda spray, the most successful solution being 

 5 lbs. of white arsenic. 5 lbs. of carbonate of soda boiled in 10 gal. of water, 

 and additional water to make 100 gal. The total cost of the si^raying is given 

 as $2.30 per acre. 



HORTICULTURE. 



[Horticultural investigations in Guam J, J. B. Thompson (Guam Sta. Rpt. 

 1914^ PP- 0-14, pt^- 2). — Notes are given on the culture and adaptability of 

 many of the common vegetables under conditions in Guam. Thus far the ordi- 

 nary commercial varieties of tomatoes have failed to grow. Results during 

 the past season with the Texas Bell, a strain of the cheri'y tomato, indicate 

 that this variety will succeed and that a fixed type of tomatoes may be developed 

 for Guam by selecting and breeding from the largest fruited plants of Texas 

 Bell. 



The pi'opagation of mangoes at the .station (E. S. R.. 31. p. 441) was con- 

 tinued during the year, and a limited nimiber of inarched plants have been 

 distributed to planters. It was demonstrated that by using iiroper jjrecautions 

 to prevent undue evaporation large mango trees may be successfully trans- 

 planted. 



Report of the acting horticulturist, C. J. Hunn {Hawaii Sta. Rpt. 1914. 

 pp. 29-35, pis. 2). — In a previous report (E. S. R., 30, p. 841) on the work of 

 breeding papayas with the view of eliminating male trees, one type was secured 

 which yielded 94 per cent fruit-bearing trees out of 343 F2 trees. Additional 

 data show that out of 4.^4 of those F- trees Avhich has fruited 95.37 i)er cent 

 were fruit bearing, thus indicating that with the continuation of the breeding
