540 KANSAS CITY REVIEW OF SCIENCE. 



In Canada Geological Survey, 1887-78, Mr. G. M. Dawson intimates the 

 occurrence of Triassic rocks in British Columbia, but he is not specially descrip- 

 tive. 



In Canada Geological Report, 1878-79, Mr. G. M. Dawson discusses the 

 Triassic of Queen Charlotte Islands, including 500 feet on the shores of Houston 

 Stewart Channel, including eight species of fossils synchronous with the so called 

 Alpine Trias of Nevada. Other fossils are from Rose Harbor and Copper Islands 

 and Burnaby Strait. Prof. Dawson estimates that the overlying volcanic rocks 

 in the neighborhood of Logan Inlet, Island of Moresby, cannot be less than 5000 

 or 6000 feet. 



The above is an epitome of Jura-Trias for Western America. Fuller infor- 

 mation can be obtained from the books referred to and I hope it may assist those 

 who desire to examine the localities referred to. I was glad to see the article of 

 my friend Hallowell in the December number of the Review and hope to hear 

 from him again.

THE DEVIL'S PIT. 



' REV. JOHN D. PARKER, U. S. A. 



In Crockett county, Texas, on the divide between Devil's River ard the Nue- 

 ces, there is a cavern in the rocks that has been named the Devil's Pit. The di- 

 vide at this point is perhaps a thousand feet above the level of the river. The 

 cavern in the ground is about eighteen feet across at the top, and has the form of 

 an inverted perpendicular cone, being several hundred feet across at the bottom. 

 Perhaps a hundred men have gone to the cavern with the purpose of being let 

 down into it, but concluded when they saw it that some one else might have the 

 glory of explorirg it. Recently a man was found who had the nerve to see if the 

 cavern was rightly named. As he passed down by a rope held firmly above, he 

 found the bees had made their hives in the sides of the rock. He declared there 

 were tons of honey in the cavern. If the air had not teen rather cold he could 

 not have gone down without being stung. About ninety feet down he found a 

 small live oak tree growing on the side of the cavern, the roots fast in the rocks. 



When he had been let down one hundred and eighty feet he came to the top 

 of a mountain of rock in the shape of a solid cone — a cone within a hollow in- 

 verted cone — with plenty of room between them to explore the cavern. So he let 

 go of the rope and went down the sides of this mountain about a hundred feet, 

 when he came to a lake of water. This water appeared to be deep, but he had 

 no means of measuring its depth. A canteen was let down to him, which he 

 filled and brought up. The water was clear and agreeable to the taste. On the 

 outside down the hill the water seeps out of the rocks, and people now think it 

 is the outlet of the lake in the cavern. Whether the water has gathered in the
