410 EXPERIMENT STATION RECORD. 



year endinr;- June 30, 1896. Studies have been made of blue grass seed, 

 10 s})ecies of wliicli are described and figured. The report of seed test- 

 ing shows an increase of nearly 20 per cent in the number of samples 

 tested and about 21 per cent of increase in the number of tests for 

 purity, germination, etc. Tlie ^tercentages of purity and germinative 

 ability show in most cases an increase over those of the i)revious year. 



A brief report is given on samples of barley bran and oil cakes 

 examined during the year. 



l*]at exiwriments with red clover, summer wiieat, and several legu- 

 minous forage i)lants are briefly reported. 



Seed raising, R. Fyfk {(lard. Chron., ser. 3, 20 {1896), No. 516, p. 6%.').— Brief notes 

 arc given on seed raising, and the belief that seed from certain jtortious of the plant 

 are better or truer in character is denied. 



G-ermiiiation of'iree seeds, A. C. Forbes (Gard, Chron., ser., S, 20 {1896), Xo.515, 

 2>2). ^'>oS, 559). — Practical notes are given on the germination of various tree seeds. 



Investigations of forest seeds by the experiment station at Bonn in the 

 year 1896 {Ihul. landir. I'res-se, 23 {1896), No. 87, p. 779). 



Seed control: Its aims, methods, and benefits, G. H. Hicks (7'jj. 28). — An address 

 delivered before the JNlassachnsetts Horticultural Society February 8, 1890. 



Tumbling mustard, L. II. Dewev ( U. S. Dept. Agr., Dicisio)) of Boiann Circular 7, 

 P2>. 8, fi'js. 3). — Illustrated descrijjlive notes are given of the tumbling mustard {Sisym- 

 brium altissimum), a troulilesome introduced weed. The methods of disseminatiou 

 are descril)ed and its distribivtion shown by means of a map which shows the plant 

 to be widely distributed thi'oughout the northern and eastern United States and 

 Canada. Methods arc suggested for its eradication. Tumbling mustard has been 

 proscribed by law in Minnesota. 



Brassica juncea, L. H. Bailey {Bat. Gaz,, 22 {1896), No. 5, p. 401).— Tim (question 

 is raised whether this weed is a direct importation from the Old World or a spontane- 

 ous derivation from gardens, the ])lant being somewhat cultivated under the names 

 Chinese mustard ov brown uuistard. 



"Weed destruction, A. Akxstadt {Die Belampfxng dts Uiikrautcs. Marslehen-Hal- 

 herstddt: J. Briest, 1896, pp. 43). 



DISEASES OF PLANTS. 



Fungus diseases and their treatment, W. C. Sturgis {Connecticut 

 State St((. Kpt. isfhj, pp. 106-190, jjls. 3, tables 2). 



Siinopsi:^. — Notes are given on experiments for the prevention of potato scab, trans- 

 l)lanting as a preventiA'e of onion smut, a leaf curl of Japanese plums, and 

 miscellaneous notes on powdery mildew of grapes, a melon disease, plum leaf 

 spot, hollyhoclc rust, winterkilling of peacli trees, and frost injury to jiears. 



The ex])eriments on the i)revention of potato scab reported in the 

 Annual Eeport of the station for 1894 (E. S. E., 7, p. 219) were con- 

 tinued and their sco])e somewhat extended. The effect was studied of 

 lime on the prevalence of scab, of treatment of seed planted in infested 

 soil, and of bai*nyard manure on scab production. In addition the 

 effect of corrosive sublimate on the vitality of si^routed seed potatoes 

 was investigated. In this experiment, although treated for an hour or 

 more, the sprouts are said to have been uninjured and all such plants 

 were fully a week in advance of those from unsprouted seed.
