provided there is a definite list for each grade, so that when 

 the pupils enter the fourth grade they will not have been 

 studying a few of the abundant species to the exclusion of 

 the others. Constant reviews, of course, are necessary, but 

 when the pupils really know a species a new one should be 

 taken up.

A good time to begin the study of the conifers in any of 

 the grades is late in November, four or five weeks before 

 the holiday vacation*. The subject can be gone over pretty 

 thoroughly before the term ends, and rapidly finished when 

 the winter term begins. It may well be followed then by a 

 study of the broad-leaved evergreens. 



THE CONIFERS TO STUDY. 



First Year List- 



White Pine (Pinus Strobus). Leaves arranged in clus- 

 ters of five, each leaf being long and slender and averaging 

 from 2% to 4 inches in length ; its margins are finely serrate, 

 and in cross-section it is triangular. Green in color, with 

 two or three distinct whitish lines on the two lower surfaces. 

 Bark of young twigs olive brown, covered with a brownish 

 pubescence; bark of older twigs smooth and shining. Scars 

 where the bundles of leaves have fallen tiff broadly oval, 

 sometimes nearly circular. Buds conical, with a distinctly 



pointed tip; they are rather small, averaging V inch in 



3 Tccffea 



length. Cones large, slender, 4 feel to 6 i^efrlong; scales 



resinous, whitish brown, each scale distinctly pointed ; rather 



1 While the larch is not an evergreen it is a conifer and is usually associated with 

 evergreens .
