Doctor Kki.i.kuman. Wo have, I think, uiiivorsul rooporation at 

 the present time. It has been very enthusiastir in the areas in which 

 then' is a cominrnial citrus iixiuslrv, such as smithern Texas and in 

 the Mississippi, Ahihania, and Florida regions, when^ round oranj^o 

 or Salsuina oranges or «;rapcfruit are j^rown. 



Doctor Tayu>r. 1 think it wouhl he a fair stuteinent, Mr. ('hair- 

 man, to say that tlierc has heen a very ninrked chaii<;e of attitude 

 on the part of citrus growers as this work has pr(»;;ressed. In the 

 hei^iiuHUi; they were fearful of adverse effect upon Lmd values and 

 that sort of thinj; as it became known that their j^roves were under 

 8Uspi<-ion. They have since recognized that secrecy would ulti- 

 mately result in harm, and they ar«' now very frank and prompt to 

 brinj; any suspi<-ious <"ase to the attention of the specialists. S<j a 

 very wholesome readjustment of opinion has developed. 



Mr. A.NDKKsox. Is the disease diflicult to diaj^mjse? 



Doetor r.vvLou. To distintjuish from tlie widel}' prevailing <itri)s 

 scab, which is not nearly so serious. 



DISEASES OF FOKf:,ST A\I) OKNAMKNTAL TKEES AM) SHRUBS. 



On page 80, the subappropriation for tlie investigation of diseases 

 of forest and ornamental trei>s and shrubs, there is no change. We 

 propos(^ a continuation of that work as it is. 



WHITE PINE BUSTER RUST CONTROL. 



The same remark applies to the subappropriation for white pine 

 blister rust cf)ntrol, on page 82. The only change suggested there 

 bein(]j the omission of tlie {)rovision of ?.5(),00() to l)e immediatt^ly 

 availa})le, which was necessary last year to inaugurate the enlarged 

 educational campaign in the Eastern States, upon a basis of full- 

 season activity. 



Mr. Anderson. I think you had better tell us something of wiiat 

 vou are dt)ing on this item, in view of the incr(\"i'^e in the amount over 

 last j'ear. 



PROGRESS OF WORK. 



Doctor Taylor. This is briefly referred to in the statement that 

 1 have already submitted, but it would perhaps be well for me to read 

 the paragraph for tlie committee, it appearing in that preliminary 

 statement. [Reading:] 



\\'hite-pine blister rust is a destructive plant disease that reached America about 

 l!>00. It was introduced from Europe on infected white-pine nursery stock, which 

 was planted in many places in the eastern I'nited States. In lit 13 it was found 

 attacking native white pines, but its wide distribution was not suspected until the 

 late fall of l!M">,when the rust was discovered on currant and gooseberry bushes and 

 white pines over a large area in Massachusetts and New Hamptihire. Since then, 

 in cooperation with the affected States, practical measures have been developed for 

 the control of this di.sease under eastern conditions, which consist of the eradication 

 of currant and gooseberry bushes within IKK) feet of the pines. The outstanding feature 

 of the white-pine blister-rust situation during the past year was the discovery of this 

 destructive disease in Hritish Columbia and the Puget Sound region of southwestern 

 Wa'^hington. The department, in cooperation with State and Canadian authorities, 

 has taken prompt action to determine the extent of the infected area and if jKxssible 

 to control or eradicate this new outbreak of the di.sease. The latest information indi- 

 cates that the'disease was intrixluced into British Columbia about 1910, prior to the 

 enactment of the Canadian blister-rust (luarautine.
