WINOOSKI MARBLE. 231 



Besides the Salterella I have seen bodies in the marble 

 which I have no doubt were fragments of fossils but they 

 were too imperfect to be identified. One piece however 

 contained sections of what I believe to be identical with, 

 or at least very closely allied to, the Archeocyathtis At- 

 lanticus Billings, figured and described in the above men- 

 tioned work page 4, and also on page 283 of Geology of 

 Canada. It is rather uncertain work to try to identify 

 such fragments of fossils as the rock may contain as they 

 are much broken and are mixed with great numbers of 

 similar fragments which are not fossils from which they 

 cannot be certainly distinguished. 



In addition I wish to say a few words in regard to the 

 formation in which the marble occurs beginning with the 

 marble itself. This is a dolomite containing considerable 

 silica and iron. Much of it is a breccia ; the angular frag- 

 ments are of lighter color than the cementing material in 

 nearly all cases and have obviously been but little dis- 

 turbed since broken as it is not uncommon to find several 

 fragments near together, separated, it may be, by but the 

 tenth of an inch, which evidently would fit exactly to- 

 gether could they be nioved. The better varieties of the 

 stone are very hard, compact, durable, take a high polish 

 and are ver}^ beautiful. All shades of red from the most 

 delicate flesh-color to deep chocolate brown occur, in all 

 cases mingled with pure white, sometimes in equal pro- 

 portions, sometimes the lighter colors predominating, 

 sometimes the darker. I doubt if anywhere a greater 

 variety can be found than occurs in any lot of fragments 

 of the Winooski marble. In fact it is much more diffi- 

 cult often to find two pieces from different beds exactly 

 alike than it is to find two quite different. 



Some of the slabs from the same layer of course resem- 

 ble each other quite closely, but not infrequently a block
