lu the orchard it matters little at what height the trees are banded, 

 but along highways it is best that the bands be placed at a height 

 sufficient to keep passers-by from coming in contact with them. 



Tarred paper, the kind best suited for tree-bands, is sold by 

 dealers in agricultural wares, from whom, also, preparations for 

 painting the bands can be procured. 



Haiipen-leim. — For several 3'ears a preparation of tree-ink superior 

 to those used in America has been extensively used in Germany. 

 This preparation, known as " Raupen-leini," has the advantages of 

 not being injurious when applied directly to the bark, and of 

 remaining sticky for many weeks, much longer than the substances 

 ordinarily used. The Gypsy JMoth Committee in their woik of exter- 

 minating the Gypsy Moth in eastern Massachusetts have imported 

 several tons of it, and have found it much more economical to use 

 than the preparations previously employed. 



" Raupen-leim " is now being placed on the American market 

 under the name of " Insect Lime," and we have received circulars 

 advertising it from Wm. Menzel & Son, 64 Broad street, New York, 

 N. Y. The Bowker Fertilizer Company, 43 Chatham street, Boston, 

 Mass., has also made arrangements to furnish it. 



Tree Protectors, Traps, etc. — Besides the simple methods of 

 banding, numerous contrivances known as Canker Worm traps and 

 tree protectors are often made use of. They consist of a trough to 

 contain an oily liquid, protected by a roof of some sort, so secured 

 about the trunk that no insect can pass. If proper precautions are 

 taken to leave no crevices when putting them on and to keep the 

 trough filled with oil and free from extraneous matter, they are a 

 sure protection and at the same time less troublesome to care for than 

 the ordinary bands. On account of their costliness, however, they 

 are little used except on ornamental trees on private estates where 

 appearances are of more import than economy. 



Cotton Bands. — Cotton batting in strips about four inches wide, 

 tied securely about the trunk, has been found by Miss Mary E. 

 Murtfeldt* to be a cheap and effective barrier to the moths. The 

 insects become entangled in the fibres and die from exhaustion. The 

 bands should be examined every two or three days and the eggs and 

 living moths crushed. This kind of barrier, if kept on through the 

 winter, would probably need to be renewed or at least combed out in 

 the spring. It should also be frequently examined to see that it has 

 not become torn or blown away.
