The progress of the disease is checked by tapping, burning, and tarring. 

 Old wounds and rough places on the bark seem to afford an easy entrance to 

 the fungus, so these should also be tarred. 



A parasite occurring- in the latex of Euphorbia pilulifera, A. Lafont 

 iCompl. h'ciid Sac. Biol. [Paris], 66 {1909), A"o. ,?.?, pp. i (; J/-/ 0/5 ).— Attention 

 is called to a disease of this ornamental Euphorbia which causes a premature 

 shedding of its leaves. On examining the affected tissues, a species belonging 

 to the group FlagellatjB was found infesting the latex of the attacked plants. 

 The organism is described as Lcptomonas davidi n. sp. 



Some parasitic fung-i on greenhouse plants, E. Griffon and A. Maublanc 

 (Bui. Triiiicst. Soc. MycoJ. France, 25 (1909), No. //, pp. 238-2.',-^, pi. i).— The 

 authors discuss 4 diseases of hothouse plants, of which Pestalozzia clusice 

 on the leaves of Clusia sp. and PliyUosticta draccenw on Draciena leaves are 

 described as new. Codiseum plants were found to be injured by two fungi, 

 GIOEOsporium soraucrianum, which is claimed to be identical with G. crotonis, 

 and Asteroma codiaH, a violet-colored fungus associated with the Glceosporium 

 on the stems and limbs of the CodijBum. 



A carnation disease, H. Blin (Rev. Hort. fPf/m], 82 {1910). No. 5, p. lO/f). — 

 This is a brief discussion of a leaf disease of carnations due to the parasitic 

 fungus Hetcrosporiuni ecliinulatum, which is said to have caused much damage 

 during 1909 in yarious portions of France both to outdoor and hothouse plants. 



A'arious fungicides are recommended as means of combating the disease.

National bird and mammal reservations in Alaska in charge of the U. S. 

 Department of Agriculture (U. S. Dept. Agr., Bur. Biol. Surrey Circ. 71, pp. 

 lij, maps N). — The executive orders setting aside these reservations are pre- 

 sented, together with maps which show the exact territory embraced in each. 

 These reservations, established in February and March, 1909, comprise, with 

 one exception, small islands along the coast of Alaska and in the Bering Sea, 

 and are known respectively as Bering Sea, Fire Island, Tuxedni, Saint Lazaria, 

 Y\ikon Delta, Pribilof and Bogoslof reservations. " Fire Island is the breed- 

 ing ground of the Alaska moose, the islands in Bering Sea contain rookeries of 

 sea lions, and all of "the reservations are important breeding grounds of sea 

 birds or ducks and geese."
