On September 2, 1919, with a parl>- of xisiting geologists, I 

 had a boat ride on the reservoir from which water is pumped to' 

 most of the iron furnaces and roUing mills of the Tennessee Coal, 

 Iron & Railroad Co. in the vicinity of Birmingham. It was con- 

 structed eight or nine years ago by building a dam about 90 

 feet high across Village Creek just above the mouth of Venison 

 Creek, about three miles southwest of Adamsville, in Jefferson 

 County, Alabama, in latitude 33° 34', and about 500 feet above 

 sea-level. This creek is a tributary of the Locust Fork of the 

 Warrior River, and the dam is about twelve miles from the river 

 by the course of the creek, which flows in a general northwesterly 

 direction. 



On the shady side of the reservoir, with a northeasterly .ex- 

 posure, and also in the gorge just below the dam, we noticed 

 several specimens of the tree in question. I did not have time 

 to go down the creek below the dam, but judging from the avail- 

 able topographic maps conditions should be favorable for the 

 hemlock all the way down to the river. The whole country from 

 there to Tuscaloosa is in the Warrior coal field, characterized 

 by shaly sandstone of the upper Carboniferous. This creek, 

 like several other tributaries of the Locust Fork, takes its rise in 

 a limestone valley, but that may have little to do with the oc- 

 currence of the hemlock. 



At one point a long-leaf pine, Pinus paliistris, was noticed on 

 the sunny side of the reservoir directly opposite some of the hem- 

 lock and scarcely a stone's throw away. That pine is common 

 on many hills and mountains in Jefferson County, and extends 

 inland to the northern part of Walker County,* but this is 

 probably the first time that its range has been recorded as over- 

 lapping that of Tsuga Canadensis. Incidentally, there seems to 

 be a wide gap between the knowm stations for the latter in Ala- 

 bama and those in Georgia and Tennessee, a fact not easily 

 explained at present. — Roland M. Harker.
