of the sirnp had been removed. Studies were made of this mold, and it was 

 found to be a species of Torula closely related to T. sacchari-lactis, from which 

 it differs in the average size and color of the spores and the ultimate branchlets 

 and in the absence of the delicate prickles. The fungus is supposed to be an 

 undeseribed species and is named T. saccharina. The characters of the fungus 

 grown in various cultures are described at length. 



Analyses were made of various sirups to determine whether the molding of 

 the (different kinds of sirup was due to the low sugar content. It was found 

 that by Increasing the total sugar content the growth of the Torula was 

 nearly inhibited, and it is evident that market products should be made more 

 concentrated than is the common practice.

The Alaska game law and regulations of the Department of Agriculture, 

 1908 ( U. /S'. Dei't. Agr., Bur. Biol. Survey Virc. 66, pi). 8).—" Under the new law, 

 approved May 11, 19GS, Alaska is divided at latitude 62° into two game 

 districts, with special seasons for each district. Caribou on the Kenai peninsula 

 are protected until 1912. Nonresidents hunting big game other than deer or 

 goats and residents desiring to export heads or hides of big game from 

 Alaska are required to obtain licenses. Authorization is also given for the 

 employment of wardens and registration of guides. All matters relating to the 

 issue of licenses, employment of wardens, and the registration of guides are 

 placed in charge of the governor of Alaska. . . . The Department of Agri- 

 culture will continue as heretofore to issue permits for the collection and 

 shipment of specimens for scientific purposes and for live animals and birds 

 for exhibition or propagation." 



The text of the new law and the regulations prescribed by this Department 

 to take effect Oetoiier 1. IDO.S, are given.

 also shows the date of establishment of each State commission or wardenship, 

 the changes which occur in such offices, and the publications issued by game

The use of bacteria in destroying rats, Xylandeb (Ztschr. Fleisch u. Milch- 

 hyg., 18 (1908). Xo. 8, pp. 2///-2-}5 ) .— The literature relating to the various 

 l)acterial cultures which have been used in destroying rats is critically 

 reviewed. The author considers that at the present time it has not been 

 demonstrated that any of these cultures are invariably harmless for animals 

 other than rats. 



Exterminating field mice with barium carbonate, L. Hiltner and G. Korff 

 {I'rakt. BJ. Pflanzeiibitu u. Seltutz., n. ser., 6 (1908), Xo. //, pp. 31-J,0).~ 

 A number of experiments were made with two kinds of virus designed for 

 the destruction of mice. The results were fairly satisfactory. Samples 

 of virus were distributed to various individuals but only two reports were 

 received both of which were favorable. On the whole, however, the method 

 of using poisoned baits is more efficient. The best results were obtained 

 from the use of barium carbonate in an attractive bait. This remedy was 

 tried in various localities with good success.
