A new species of coffee from German East Africa, W. lirssK ( Trupenpjianzcr, 

 6 {1'JO..'), .\(i. .!, ]>[). l.'iJ-14'h fi'J- 1) ■ — -•^ 11^'^^' i^pecies of coffee (('o//m srlnnnnmiimia) 

 found in (Jermaii East Africa is described. It differs from ('. anibica in that the 

 latter has thicker leaves, more abundant bloom, larger fruit, and longer seed. 



Bush fruits, F. AV. Cakd {Rhode Island ,^ta. Ihil. 91, pj). 89-ll<;, pis. .f). — Besides 

 some work with fertilizers for blackberries and raspberries and an account of the 

 variation of jdelds with different plants and different varieties, which have been 

 jjreviously noted (E. 8. 11., 13, j). 740), data are given on the yields of varieties in 

 hills and in hedges and on the culture of l)luel)erries. AVhen red raspberries and 

 blackl^erries were grown in hedge rows nearly 3 times as heavy yields were obtained 

 as when they were grown in hills. Crimson clover was tried as a cover croj) for 

 berries and gave very promising results. The strawberry weevil was found doing 

 considerable damage to wild blackberries, but was not present to any extent in 

 cultivated patches. Early Cluster and Taylor blackberries, Kansas, Eureka, and 

 Nemaha black raspberries, and Cuthbert red raspberries have been found the most 

 satisfactory varieties of these berries thus far grown. Experimental work with these 

 fruits shows that in cnjssing it is necessary to remove the stamens of the flowers to 

 prevent self-fertilization. Attempts have been made to propagate the swamp blue- 

 berries ( VaccAnhun corymbosum) by means of root cuttings, stem cuttings, and root 

 grafts. These attempts have been only moderately successful, for while shoots 

 were readily produced it was difficult to get the plants to root. Better results were 

 secured when soil was used in which the blueberries had been previously grown. A 

 fungus is nearly always found growing with tlie roots of the l)lueberries, and it is 

 suggested that this fungus, together M'ith an acid condition of soil, may be one of 

 the essential conditions to the best development of blueberries. 



Notes on small fruits, JM. L. Dean {Mk-hujun Sla. Bui. 206, pp. 51-60). — Xotes 

 are given on a number of varieties of strawberries, raspberries, blackberries, (urrants, 

 and gooseberries grown at the station during the season of 1902, with descriptions 

 of some of the most })romising varieties. 



The Lucretia dewberry, J. B. Gilchrist {Delaware Slate Bd. Agr. Rpt. 190.', pp. 

 112-114) ■ — The author exi^erimented with a number of systems of training the dew- 

 berry, as a result of which he has settled on the following method: No. 12 galvanized 

 wire is stretched taut on cypress posts 3J ft. long and driven 18 in. into the ground. 

 The vines are trained on this wire. About 6 vines are left in each hill. Each 

 branch is cutoff about 4 ft. long and wound around the wdre 2 or 3 times, 3 l)ranches 

 in each direction. The vines are fastened to the wire by a single piece of fine wire 

 in the center. Thus treated, the approximate cost of growing an acre of Lucretia 

 dewberries is placed at 179.50. The average net receipts per acre for 4 years has 

 been $70.61 and the average yield 2,G40 qts. 



Strawberries for forcing, C. E. Hunn {xVmer. Florid, 20 {1903), No. 781, pp. 640, 

 641, fig- !)■ — The author considers Beder Wood the earliest variety of any value for 

 forcing. The next in succession is Glen JNIary which, all things considered, is the 

 best variety ever used for forcing in the author's experiments. Other good varieties 

 for forcing are Brandy wine and Sharpless. Of 20 new varieties tested during the 

 past winter but one, the President, proved of value for forcing. 



Nitrate of soda in the culture of grapes, G. Chappaz {Prog. Agr. et V'd. {Ed. 

 L'Est), 24 {1903), No. IS, pp. 645-560) .—i:\w. effect of the different forms of nitrogen 

 as represented in manure, nitrate of soda, and sulphate of ammonia, respectively, on 

 the yield of grapes and quality of wine produceti is being studied experimentally.
