AMERICAN FORESTRY 



eighteen inches long and two inches deep. Over the chart 

 showing the tree physiology is placed a sheet of cellu- 

 loid, as is also the case in covering the leaf, the leaf first 

 being placed on cotton, celluloid over same and then 

 tacked to the specimen case as shown in the illustrations. 



It will be a good plan for all Forest Guides to build 

 up exhibits for their troop meeting-rooms. Some can 

 build the cases, others can collect the specimens, all can 

 help to make up the cases. Write to J. S. Illick, the 

 Department of Forestry, Harrisburg, Pennsylvania, ask 

 him to send you the book, "Trees of Pennsylvania," which 

 will help in your study of trees and in the building of 

 the cases. 



The editor built nine cases and presented them to the 

 National Headquarters of the Boy Scouts of America, 

 at the biennial conference of the scout executives of the 

 United States. He also recently built a number of these 

 cases for use in the Scoutmasters' Training Course, by 

 Dr. Hurt, the scout executive of Chicago. 



In the June issue of the American Forestry Maga- 

 zine, we will have a story on insect life, and will also 

 show and tell you how to mount and preserve specimens 

 of wild flowers, weeds, and so forth. 



To those who have written to me and whose letters I 

 could not answer, owing to my illness, I want to say in 

 these columns, that I shall now begin to answer the mail 

 that has been accumulating for several months, and that 

 with the June number of the American Forestry Maga- 

 zine, we will open the question box to help you along in 

 your Nature work. 



Anyone interested in the Forest Guide Movement, 

 and who wants to join, no matter where, or in what part 

 of the United States you may live, is invited to write to 

 the editor of this department, Solan L. Parkes, Editor, 

 Forest Guide Department, Post Office Box No. 9, Read- 

 ing, Pennsylvania, inclosing a two-cent stamp for answer. 



BLIGHTED CHESTNUT 



At the upper left, the physiology of the chestnut tree on a chart. In 

 the center top, a small branch showing the live spores of the chestnut 

 blight. To the right, a leaf of the chestnut tree. In the center a branch 

 which shows the results of the blight. At the bottom the grain of the 

 wood of the chestnut, healthy bark, a panel of commercial timber, a 

 cross section and a bottle of seed, fruit or nut, while at the extreme 

 lower right hand corner is the chestnut burr. 



THE SASSAFRAS 



The seed or fruit, cross section, bark and panel, and for those who do 

 not know, the three leaves taken were from a branch of the sassafras 

 tree. At the top of the case, a leaf with but a single lobe, in the 

 center two lobes, or what is sometims termed as the sassafras mitt, 

 at the bottom a leaf with three lobes. The writer has found as many 

 as five lobes on a single leaf.
