vicinity. On tlie College grounds two trees grow east of the south end of Col- 

 lege hall, also in ii grove west of the chemical laboratory, where tliey may be 

 coiiipaivd with Scotch pines, which are of a lighter color and of a more deli- 

 cate habit. 



PINE, BANK'S. 



See gray })ine. 



PINE, BLACK. 



See gray pine. 



PINE, BUCKWHEAT. 



See gray pine, and perhaps white pine. 



PINE, CEMBRIAN— Pmws Cembra. 



This very beautiful and symmetrical tree comes from the Alps and sur- 

 rounding country, consequently it endures our coldest winters without injury. 

 It will grow on almost any kind of soil, but does best on a deep rich soil, Like 

 the white pine its leaves are in clusteis of five. The leaves are shorter and of a 

 darker color; the bark is also darker, the growth much slower, the limbs much 

 denser when compared with tlie ti'ee last mentioned. Its slow growth is the 

 greatest objection to its use as an ornamental tree, but even this peculiarity is a 

 meiit in small places or near dwellings. The fertile cones when in flavor are 

 of a bright, purple color, and when a little older have a glaucous bloom 

 resembling a plum. The wood is fine granied and is much used by the Swiss 

 for carving into toys. The seeds are palatable and eaten as we eat filberts and 

 almonds. Oil is also pressed from the seeds. A tree stands just near the north- 

 west corner of College hall, also one about four rods southeast of the house of 

 Professor Beal. 



PINE, CROCODILE. 



See gray pine. 



PINE, DWARF— Ptnus pumilio. 



This tree scarcely ever attains a height of more than ten or fifteen feet. If 

 left to itself, it generally falls over and becomes a trailing shrub, four feet high, 

 spreading in all directions. The leaves are two or more inches long, and of a 

 dark green color. It is perfectly hardy, and is one of the most valuable of 

 evergreens to place in groups or in small yards, or even as a single specimen in 

 a hollow or on a slight elevation or on the ui)per edge of a clitf or roekwork. 

 With me it is a great favorite. It is a native of the Alps. A good specimen 

 grows at the College about fifteen feet north of college luiU, also in the group 

 east of the chemical laboratory, and in numerous other places. 



PINE, GilKY—Plnus Banksiana. 



Tiiis small tree goes by a great variety of other names among the people of 

 Michigan, such as scrub, black, crocodile, Jack, buckwheat, etc. It is a 

 scrubby bush or small tree, though it often becomes fifty or even eighty feet 

 high, and fifteen inches in diameter. It grows in poor sandy soil. It is rather 

 more slender and graceful than the Austrian pine, which it somewhat resem- 

 bles. The leaves are short and of a dark color. The grey pine is not often
