mental planting. It proves hardy in the southern part of the state. 

 It is a fast growing tree, adapted to a wet soil, but will succeed in drier 

 situations. 



5. THLiJA. Arbor-vitae. 



Thuja ocfidentalis linnaju.s. Arbor-vitae. Plate 8. Small 

 evergreen trees with a conical crown, bark on old tiees reddish-brown 

 or dai'k gray, shreddy; liranchlets compressed, reddish-brown; leaves 

 all closely ajjprcssed, in alternate pairs, scale-like, about"3 mm. long on 

 young l)i-anchlets, on old branches somewhat longer together with a 

 spine 2-3 mm. long; flowers appear carl}' in the spring from the ends of 

 the bi-anches; cf)iies mature the first season, about 1 cm. long and ..5 

 cm. in diameter; wood soft, brittle, weak and durable. 



Distribuiioii. — New Brunswick to Manitoba, south to Minnesota 

 and New .Jeisey thence southward along the Alleghanies to North 

 Carolina and Tennessee. In Indiana it is found native' only in Lake and 

 Porter Counties. In Lake Count}' a few isolated specimens have been 

 foun<l in sevei'al places near Lake Michigan. In Porter Countj' it is 

 known only in a large tamarack swamp north of the Mineral Springs 

 stop on the Traction line, and about a mile from Lake Michigan. 

 Here aljout 100 trees are found scattered over an area of less than two 

 acres. The largest specuiien measures 70 cm. m cn-cumference. This 

 species IS doomed to early extinction in our area. No doubt it already 

 has vanished from Lake County, and it is probal)le that the colony 

 nortli of Alinei'al Springs is the last of the species in Indiana. 



Reniark.s. — While only found in a swamp in Indiana, this species 

 adapts itself to all kinds f)f soils and exposures. It transplants readily 

 and is used for ornamental purposes, and for windbreaks. Dwarf forms 

 are frequently planted foi' hedges. The wood is used principallj' for 

 poles and posts, and is commercially known as white cedar.

Evergreen shiiibs or trees, leaves opposite or whorlecl, sessile, scale- 

 like 01- short -lineal-; fruit berrj'-like; seeds 1-3. 



,Jiini])crus virginiana Linnjeus. Red Cedar. Plate 9. A 

 small tree, usually 1-2 dm. and rarely up to 5 dm. in diameter; bark 

 shreddy; branches usually more or less ascending which gives the tree 

 a narrow conic appearance; shoots green, soon turning light to reddish- 

 brown and on older branches gray or dark brown; leaves 4-ranked, scale- 

 like and 1..5-2 mm. long, oi- subulate, decurrent at base and 3-10 mm. 

 long on vigorous branches or very small trees; flowers tei-minal; fruit
