240 EXPERIMENT STATION EECORD. 



of 4 experiment fields are given and results of inoculation of lupines and soy 

 beans presented in tabular form. In spraying experiments Bordeaux mixture 

 and Cucasa, a proprietary mixture, resulted in appi'oximately equal yields. A 

 brief review of grain breeding work is given. 



Some analyses of seeds, G. Gassner {Rev. Secc. Agron. Univ. Montevideo, 

 1908, No. //, PI). 101~ury; Rev. Inst. Ayron. Montevideo, 1900, No. 5, /</>. 95^ 

 105). — Germination and purity tests of samples of seed of alfalfa of 9 differ- 

 ent classes are given in connection witb tbe market price and cultural value of 

 tbese seeds. Dodder {Gusenta rucemom) was found only in tlie seed from 

 Argentina, but tbe opinion is expressed tbat seedsmen prevented tbe securing 

 of representative samples. Tbe percentage of impurity reported ranged from 

 0.83 to 3.54 per cent. Tbe cultural value reported, wbicb is tbe product of 

 tbe purity percentage and tbe germination percentage, ranged from 56.14 to 

 92.17 per cent. 



Tbe germination percentage of 6 varieties of clover and tbe principal im- 

 purities present are reported in tabular form. Tbe cultural value ranged 

 from 12.8 to S2.7 per cent. 



Impurities of grass and clover seed sold in Virginia, Gertrude B. De 

 Loach, L. Carrier, and T. B. Hutcheson {Virginia Sta. Bui. /.S',, /^/>. .3-18, 

 figs. 14). — Tbe results of purity and germination tests of red clover, crimson 

 clover, timotby, redtop, and orcbard grass are presented in tabular form and 

 lists of tbe principal weed seeds found in eacb given witb a statement of tbe 

 frequency of occurrence of eacb kind of weed seed, and discussion of metbods 

 of testing seed in tbe laboratory and on tbe farm. 



Trials with spraying machines for iron sulphate solutions, 1909, C. V. 

 BiRK and M. Dall (Tidsskr. Laiidokonomi. 1009, No. 12, pp. 6.'i9-667. figs. 2). — 

 Brief descriptions of seven power or band spraying macbines tested and found 

 to do satisfactory work witb iron sulpbate and Bordeaux solutions are given. 

 Tbe strong and weak points of eacb are indicated in a summary of tbe 

 opinion of tbe judges. 



References to recent work in plant breeding, G. Fruwirth {Jour. Landw., 

 51 {1909), No. 3, pp. 281-306). — A review is given of numerous publications on 

 plant breeding. 



HORTICULTURE. 



Report of the horticulturist, J. E. Higgins {Haicnii ^ta. Rpt. 1909, pp. 

 Jfl-.')7, Ills. 3). — In addition to tbe marketing e.xperiments witb pineapples pre- 

 viously noted (E. S. R., 21. p. 45). considerable attention was given to metb- 

 ods of propagating citrus fruits and mangoes, and studies were begun to de- 

 termine tbe most satisfactory metbods and season for budding tbe avocado. 



Tbe causes wbicb are believed to be cbiefly responsible for tbe numerous 

 failures reported in budding citrus trees are given as poor bud wood, lack of 

 vigor in tbe stocks, and insect attacks. Scale insects and mealy-bugs were 

 combated more successfully and cheaply by fumigating witb hydrocyanic-acid 

 gas tban by tbe use of kerosene emulsion. Remedies are also suggested for 

 climbing cutworms, Archis postvittanus, and apbids. It is recommended tbat 

 those wbo bave difbculty in budding sbould adopt tbe sbield metbod witb tbe in- 

 verted " T," so successfully used in propagating tbe mango (E. S. R.. 22, 

 p. 642.) 



Citrus stocks of rough lemon, sweet orange, sbaddocks, and seedlings from 

 California grown pomelos are being tested, eacb important variety of orange, 

 lemon, or pomelo being budded on eacb of tbese stocks. Buds inserted during 

 January, February, March, aud April appeared to be equally successful, pro-
