QUARANTINE h2h^JS DIVISION 



EEPORT FOR THE MONTH OF JANUARY, 1914. 



By Frederick MaskeW;, Chief Deputy Quarantine Officer, San Francisco, California. 



The quarantine service has made a new alliance and a valuable one, 

 during the past month. The Forestry service of the United States is 

 now co-operating with the quarantine officers in the detection and 

 determination of plant diseases likely to prove injurious to the forest 

 growths and commercial plantings of trees destined for economic pur- 

 poses in the United States. This was brought about by the detection 

 of serious fungous diseases upon chestnut trees imported from Japan, 

 and through the co-operation of Dr. C. L. Marlatt of the Federal Horti- 

 cultural Board who had requested the writer to report any such findings 

 by the California quarantine officers to Dr. Haven Metcalf, Pathologist 

 in charge of the United States Bureau of Plant Industry. In the 

 instance in question this was done, and the Bureau promptly responded 

 by sending Dr. E. P. Meinecke to co-operate with the State quarantine 

 officers in locating and destroying all the infected material in the ship- 

 ment ; all of which makes for progress and solidarity in this work of 

 protecting our crops.
