apart as Brooklyn, N. Y., and Mobile, Ala., get part of their water 

 supply from streams in which Chamcecyparis grows; and the water of 

 Dismal Swamp — one of the best-known localities for this species — used 

 to be preferred for drinking purposes on ships sailing from Norfolk 

 on long voyages. Tire manufacture of paper is an industry which 

 seems to require good water in large quantities, and the only paper mills 

 in the coastal plain known to the writer (viz., at Hartsville, S. C, and 

 Moss Point, Miss.) have juniper growing in their immediate vicinity. 



The relations of this species to fire have been little studied, but 

 what evidence there is seems to indicate that they are much the same as 

 in the case of the boreal forests already described. 



The wood is very durable, and therefore used largely for poles, shin- 

 gles, woodenware, etc., but it is not separated from that of arbor-vitas 

 and red cedar in the latest census returns. 



The Scrub Pine (Pinus Virginiana) , also known as Jersey pine, 

 spruce pine, nigger pine, cliff pine, etc., bears considerable resemblance

to the jack pine previously mentioned, but does not grow within 200 

 miles of it. It ranges from just south of the terminal moraine in New 

 York and Indiana to central Alabama, nearly always forming dense 

 groves or thickets with little admixture of other trees. It is common in 

 the coastal plain of Virginia north of the James River, but farther south 

 seems to be confined to the highlands. In Alabama its distribution is 

 approximately coextensive with the coal region, where it is a familiar 

 feature of the landscape. It grows in rather dry, poor, often rocky soil, 

 but not quite the poorest. In Maryland and Virginia it is very common
