44 EXPERIMENT STATION RECORD, [Vol.25 



Data are also given showing tlie results secured from trees sent out by the 

 state nursery during four seasons. 



The junipers and their commercial importance, W. Dallimorr {Roij- Bot. 

 Garcl. Kcw, Bui. Misc. Inform., No. 1 (WIG), pp. i6-23).— Descriptive notes 

 dealing with cedar woods in a previous article (E. S. R., 29, p. 842) are here 

 extended, and descriptions are given of other species of juniper not so well 

 known commercially as cedar. 



Rattan supply of the Philippines, J. R. Arnold (f7. S. Dept. Com., Bur. 

 Foreign and Dom. Com., Spec. Agents Ser., No. 95 (1915), pp. 40). — A statistical 

 report on the supply of Philippine rattan and its suitability as to quality, cost 

 of exploitation, etc., for placing in quantities on the export market. 



Wood-using industries of West Virginia, compiled by J. C. Nkixis and J. T. 

 Harris [W. Va. Dept. Agr. Bid. 10 (1915), pp. Ui'i)- — This embraces the re- 

 sults of a study of the wood-using industries of West Virginia, conducted 

 cooperatively by the Forest Service of the U. S. Department of Agriculture 

 and the State of West Virginia. Information is given relative to the principal 

 woods of the State ; the kinds and amounts of woods used in the industries, 

 including those grown in the State and out of the State; and the uses of the 

 various woods. 



By-products of the lumber industry, H. K. Benson {V. S. Dept. Com., Bur. 

 Foreign and Dom,. Com., Spec. Agents Ser., No. 110 (1916), pp. 68, pi. l,flys. 10). — 

 This bulletin embraces the results of a survey relative to the utilization of the 

 by-products of the lumber industry in the United States. Consideration is 

 given to the utilization of wood in the wood-distillation industries, pulp manu- 

 facture, and tannin-extract manufacture. The other industries discussed are 

 the manufacture of ethyl alcohol, producer gas, oxalic acid, plastics, and 

 needle oils. A general account is given of methods and processes employed, 

 together with data showing the extent of the industries. 



An efficient system for computing timber estimates, C. E. Dunston and 

 C. R. Gaevey (Forestry Quart., Uf (1916), No. 1, pp. 1, 2, pi. 1).—A simple 

 device for holding timber estimate sheets and volume tables when computing 

 estimates on adding machines is here illustrated and described. 



DISEASES OF PLANTS. 



Work connected with insect and fungus pests and their control, W. Rocson 

 (Imp. Dept. Agr. West Indies, Rpt. Agr. Dept. Montscrrat, 191/f-15, pp. 18-20). — 

 The staining of cotton is thought to be due to some organism nut yet identified 

 which is given entrance by the stainer insect when it pierces the boll in order 

 to extract the juices from the seed. A number of other injurious insects are 

 reported upon. 



Experiments with Bordeaux mixture for control of loaf rust of peanuts 

 (Uredo sii.) resulted in an increase of yield. This outcome was in contrast with 

 that of two previous tests, which were, however, made later in the season. 



Pvccinia maydis, not previously recorded here, was noted as general in one 

 field. A field of young maize plants to leeward of an old infected field showed 

 pustules of the fungus three weeks after the time of its planting. 



Tephrosia Candida was attacked by Neocosmospora vasinfecta. 



Flower heads of imphee (sorghum) were reported to be attacked by Sphaeelo- 

 theca sorglii. The formalin treatment (1 lb. to 30 gal. water) is said to be con- 

 veniei'.t and safely preventive. 



Damping off of onion seedlings in the seed bed, caused by a fungus or fungi, 

 is said to be prevented by thoroughly heating the soil for some time or by use
