51. Pinics resiriosa, of Aiion. — li'-d Pine. 



This is a large tree, the bark smoother than in the White Pine, 

 the leaves more rigid, and the cones shorter and more solid. 

 The leaves are in pairs each one half round, starting from long 

 sheaths at the base. The cones often grow in bunches, are egg- 

 shaped about two inches long, their scales without points are 

 widened in the middle. The leaves are five or six inches in 

 length. By these characteristics the true Red Pine, which is 

 often called by other names, may be distinguished. It is a very 

 valuable tree, often found growing with the other species of Pine, 

 on the dry sandy ridges in the northern and central portions of 

 the State. It takes its name of Red Pine from the color of thebark 

 which has a deeper red than any other species. One name often 

 given it, Norway Pine, is very improper, as it is entirely unlike 

 the tiee known in Europe by that name. The flowers appear in 

 the spring, and the cones come to maturity at the end of the 

 second season. 



52. Pinus mitis^ of MicJiaux. — Yellow Pine. 



This tree is common about Green Bay, and on the bluffs of 

 the Lower Wisconsin river, which may be regarded as the south- 

 ern geographical limits of the species in this State. A few trees 

 were recently (perhaps still) growing on a bluff of sand-stone, 

 ten miles west of Madison. But at the south this tree is abun- 

 dant. It is valuable for lumber, timber, etc., but inferior to the 

 White Pine, and far less common. From the Red Pine, which 

 the present species most resembles, it may be known by the 

 leaves, which are more soft and slender, and are channelled ; the 

 scales of the cones, slightly enlarged at the end, and tipped with 

 a minute weak prickly point. 



The names of white and yellow, applied to the Pines, have re- 

 ference to the color of the wood. 



53. Pinus sfrohus, of Linnceus. — Wliite Pine. 



This is the common Pine tree from which most of the lumber 

 is manufactured in the central and northern portions of Wiscon-
