THE FOREST. 



PEODUCTS OF MICniGAN xVT THE CENTENNIAL EXPOSITION. 



BY PROF. W. J. BEAL OF THE STATE AGRICULTURAL COLLEGE. 



This collection consists of : 



First — Cross sections of trunks of our native trees and some prominent intro- 

 duced species, all of ■\Thicli grow to be over six inches in diameter. The sec- 

 tions, about sixty-five in number, are from seven inches to two and one-half feet 

 in diameter (in one instance reaching seven and one-haK feet), and about one 

 and a half inches thick or long. 



Second — A collection of about one hundred and forty blocks and twigs, not 

 over six inches in diameter by about six inches in length, with bark mostly on 

 them. Some of these specimens are of shrubs, quite small, not over one-fourth 

 of an inch in diameter. One-sixth of one side of these blocks is planed off ver- 

 tically ; an oblique section is made upon the same side toward the top, leaving 

 the upper surface a little more than half the diameter. 



Third — A collection of polished boards, eight by sixteen inches, and a half 

 inch in thickness, in cases where the trees were of suflScient size to admit of it. 

 From smaller trees and shrubs the boards are ten inches long, and of a varying 

 width. The number of boards of each species varies from one to twenty, accord- 

 ing to the importance, beauty or peculiarities of the species. These boards are 

 as unlike each other as is possible to find them, for the purpose of exhibiting the 

 wood in all its peculiarities. 



Fourth — There are some specimens of other dimensions not uniform in shape, 

 size or finish. These include samples of the valuable hard woods, as oak, hick- 

 ory, etc., cut in a variety of shapes. The collection includes knots, natural 

 grafts of roots and trunks, oak sticks with deei-'s antlers imbedded in them, 

 etc. For a detailed account consult the following list. 



Fifth — Samples of seeds and cones ; a quart or more of about fifty species. 



THE LIST OF SPECIMENS. 



Each specimen of wood has a number cut on the back or under side or end. 

 This is to avoid any mistake in case a label is rubljed off and lost or obscured in 

 any way.
