Report of the Chief of Bureau of Biological Survey for ipip. 



This report is particularly interesting in the section on the campaign 

 against predatory animals and injurious rodents. Not less than one and 

 a half million dollars were available for this purpose, namely, $592,000 

 of Federal funds and more than $800,000 contributed by States, coun- 

 ties, farmers' and stock-growers' organizations, and individuals in 

 co-operation. It is estimated that by this work a saving of live stock 

 valued at $5,000,000 and a saving of forage and crops valued at not 

 less than $14,000,000 was efifected. Some 400 to 500 skilled hunters 

 were employed in the war against stock killing animals and wild animals 

 afTected with rabies, over 30,000 having been killed and nearly $200,000 

 recovered from the sale of skins. It is stated that about $500,000 worth 

 of stock was lost by being bitten by rabid animals, and approximately 

 1,500 persons are known to have been bitten, at least 47 of whom are 

 known to have died from the consequences. The annual loss from 

 rodents is estimated at $300,000,000 and from house rats and mice 

 nearly $200,000,000. The extermination of prairie dogs has progressed 

 on nearly 2,000,000 acres of private and 3,700,000 acres of public lands. 



The new migratory-bird treaty act of July 3, 1918, and the super- 

 vision of national mammal and bird reservations come in for a lengthy 

 discussion. B. E. F.

Rock has published two papers on the arborescent flora of Hawaii. 

 In one, the arborescent indigenous legumes of Hawaii is considered 

 and is of special interest to foresters because it contains interesting 

 notes concerning the well-known Koa tree, the wood of which has been 

 exported under the name of mahogany. Rock describes two varieties
