animals, the chance that 

 those of different species 

 may happen to be brought 

 together is not so remote 

 as might be supposed. 



The most remarkable in- 

 stance of this kind that 1 

 have met with was that of 

 a white oak and a tulip 

 tree at the foot of Lookout 

 Mountain, in Walker, 

 County, Georgia. It stood 

 beside a public road that 

 passed through Ashland 

 Farm, the beautiful coun- 

 try home of Mr. Z. C. Pat- 

 ten, of Chattanooga, and 

 was widely known through- 

 out the neighborhood as the 

 Twin Tree. The stems 

 were completely amalgama- 

 ted to the height of 9 feet 

 and their girth measured 

 17 feet, breast high. The 

 portion of the circumfer- 

 ence occupied by the oak 

 was II feet and the tulip 

 tree filled out the remain- 

 ing 6 feet. Unfortunately

 averages about 2 feet. 



I was not prepared for tak- 

 ing a photograph when this 

 interesting specimen first 

 came under my notice, and 

 on my next visit, ten years 

 later, found that it had been 

 blown down by a storm 

 some years before, and the 

 trunk cut to pieces and 

 carted away. Only the 

 stump remained, reduced 

 now to the hollow ring of 

 wood and bark shown in 

 the photograph (Fig. 4). It 

 was easily recognized by 

 the shape and size of the 

 stump, and the line of un- 

 ion between the two stems 

 was distinctly shown by the 

 difference in the bark and 

 the graining of the dead 

 wood. 



Twins of the same spe- 

 cies are more common than 

 those of alien stocks, since 

 seeds of the same kind are 

 more likely to be deposited 

 together, but they attract 

 less attention, being mis-
