608 Forestry Quarterly 



boats 12, furniture 12; maple — flooring 39, handles 28, furniture 

 19, cooperage 15%. 



The bulletin is replete with information, much of it in tabular 

 form, giving a wholesale view of the wood-using industries and at 

 the same time enabling one to look up details regarding any partic- 

 ular wood or any particular article of manufacture. The qualities 

 of each kind of wood are described, and the suitability for various 

 purposes discussed. A valuable list, by species of wood, of the 

 articles manufacttued from each kind, is given, and a useful 

 classified directory of manufacturers. Seventeen educative illus- 

 trations are given, illustrating various manufacturing processes 

 and products. 



The data compiled are very readable and useful, and it is to be 

 hoped that the bulletin is given a wide circulation among all 

 dealing in forest products.

Does Cronartium Ribicola Over-winter on the Currant? By F. C. 

 Stewart and W. H. Rankin. Bui. No. 374. N. Y. State Agr. 

 Exp. Sta., Geneva, N. Y., 1914. Pp. 53, ill. 



Cronartium ribicola is an heteroecious rust fungus parasitic on 

 Ribes and the five-needled pines, especially Pinus strobus. In its 

 aecidial stage, which is known as Peridermium sir obi, it produces the 

 destructive blister rust of the White pines. On the leaves of the 

 currants and gooseberries, both wild and cultivated, it produces 

 what is known as felt-rust and is of little economic importance. 



The fvmgus is perennial in the bark of the pine trees, but the 

 fimgus cannot spread from pine to pine but must go from pine to 

 Ribes and back to pine. On the leaves of Ribes two fruiting forms 

 are developed, one of which (the uredospores) may infect only 

 other Ribes plants, while the other (sporidia from the promycelia 

 of the teleutospores) can infect only the pine. Since the leaves are 

 the only part of the Ribes plant affected, and the uredospores 

 are short lived, the fungus is believed to be unable to over-winter 

 ■on Ribes. 



The appearance from time to time since 1906 of the felt-rust on 

 the Experiment Station groimds at Geneva, but without any 

 cases of the blister-rust being discovered, led to a special investiga- 

 tion to see if the fungus could over- winter on Ribes. The experi-
