 will be sent upon application to any inspector, forester, patholo- 

 gist, or other State or experiment station officer, to any nursery- 

 men or orchardist growing chestnuts, or to any botanist or teacher 

 of botany. So far as the supply permits lantern slides and pho- 

 tographs will, upon application, be loaned for special lectures, ex- 

 hibits, etc., to the officers of States, experiment stations or colleges. 

 By these means the inspectors first, and then the general public, 

 may become familiar with the appearance and work of the dis- 

 ease in localities that it has not yet reached, and when it does 

 appear may be able to recognize it before it is too late to take 

 efficient measures against it." 



The pamphlet further states that " bark disease may be 

 confidently looked for in any orchard or nursery in the United 

 States that contains chestnut trees. All such places should there- 

 fore be rigidly inspected at the earliest possible date" as at 

 present " there is nothing in sight that promises even remotely to 

 check its spread into new territory except the general adoption 

 of the measures advocated in these pages. It cannot be argued 

 that because of its apparently recent origin and rapid spread it 

 will soon disappear of itself Such diseases as pear-blight and 

 peach yellows have been in the country for more than a century 

 and show no sign of abating except when actively combated by 

 modern quarantine methods. Nor can any conclusions be drawn 

 from the fact that chestnuts in the Southern States have suffered 

 from a disease during the past twenty years, since, as already 

 stated, that is a totally different thing from the bark disease."
