From each tree there are ent two or three h>j;s ami Iroin each k)^ three or t'onr sticks, 

 two of standard size, the other one or two of hirger size. Each standard stick is cnt 

 in two, and one end reserved for testing 2 years hater, after seasoning. The standard 

 size for the sticlcs is 4 by 4 indies and 60 inches long for cross-breaking tests. How- 

 ever, there will be made a special series of cross-breaking tests on a specially con- 

 structed beam-testing machine, gauged to the Watertown testing machine, in which 

 the full log length is utilized with a cross section of by 12 np to 8 by 16 inches, in 

 order to establish the comparative value of beam tests to those on the small test 

 pieces. It is expected that on an average iifty tests will be made on each tree, 

 besides four or live beam tests, or two hundred and fifty tests for each species and 

 site. The methods adopted for the tests will be described more fully later. 



All due caution will be exercised to perfect and insure tho accuracy of methods, 

 and besides the records, whicli are made directly in ink into permanent V)Ooks, avoid- 

 ing mistakes in copying, a series of i)h(itographs, exliibiting tlie character of tlie 

 ru]iture, will assist in the ultimate study of tho material, which is also preserved.
