12 NOTES OX THE BALD CYPRESS. 



In Tennessee the species is limited to the district west of the Tennessee 

 river, and to the borders of that stream in the lower part of its course. I 

 have been unable to find that it extends above the level of the Muscle 

 Shoals. 



In Kentucky the limitation of this species is even narrower than in Ten- 

 nessee. It is not common except in the district west of the Tennessee 

 river. It is rarely found on the Ohio river above the mouth of the Cum- 

 berland. On the Tennessee and the Cumberland rivers it is found in the 

 swamps near those streams to the State line or a little beyond. On the 

 Green river it is occasionally found, but I have never seen it in the shape 

 of connected forests. East of the Green it is unknown to me, and on that 

 stream it does not extend above the junction of the Barren river. 



North of the Ohio the cypress occurs in the swamps of southern Illi- 

 nois and southwestern Indiana; but its northward extension along the 

 rivers of those States seems to be very limited, though I have no means 

 of tracing it in detail. 



Along the main Mississippi it does not extend much above the junction 

 of the Ohio. 



"West of the Mississippi the extension of this species is much more lim- 

 ited than on the eastern side of the river. 



I have no knowledge of the species on the Missouri river, or any part of 

 Missouri, except near the Mississippi. 



The whole of the swamp districts of Arkansas, Louisiana, and Texas 

 afford it congenial stations ; and it probably occupies larger areas in those 

 States than in any others. 



Beyond the limits of the United States its extension is difficult to deter- 

 mine. It is not found in the West India Islands, and I have no informa- 

 tion of its occurrence along the Mexican shore. 



The economic uses of the timber are as yet limited. The larger knees 

 are occasionally taken for well-buckets. When of the fullest growth they 

 are hollow, their cavities being large enough to contain a gallon or two of 

 water. They are also occasionally used as bee-hives, though they are gen- 

 erally much too small to serve this purpose. 



The tree itself has long been used for the purposes to which the other 

 coarser coniferous woods are applied. The wood is easily worked, and 

 though rather brittle, is used for clapboards and other house-building pur- 

 poses. It is fairly enduring both above and below the ground level. As
