112 JOURNAL AND PROCEEDINGS 



never have deserved the impression of the main stem with the 

 branches attached gradually getting thin towards the top. One of 

 the layers, but not the large flag, contains apparently detached or 

 broken ofT branches, in addition to Hall's Lingiila oblata, which is 

 white, not colored, as in the CUnton Iron-band. 



A cliff at the foot of the Jolley Cut, near the small reservoir, 

 presented many interesting specimens from the Clinton (May Hill) 

 sandstones. A plant now in the Dominion Geological Survey 

 office represented what the late Prof. E. Billings described as "a 

 tangled mass of a cord-like alga in the shape of a pyramid." It was 

 the only one of the kind found iiere ; but in one of the quarries be- 

 yond the East-End Incline, where stonecutters were working on 

 the Medina freestone, I found a nearly allied form (slighter, how- 

 ever) which had been chipped off from the surface of a thick block 

 of sandstone. 



The cliff in rear of the reservoir furnished me with some fine 

 slabs of colored Eiugulese {Li/igiila iingulata) , described and figured 

 by Dr. James Hall, occurred in a thick iron hard rock which I had 

 to break up with a sledge. The lower green band holds at least 

 three graptolites. One of them I recognized as found previously 

 in New York State. Retiolites Venosus was figured by Dr. Spen- 

 cer, F.G.S. The frost penetrates the face of the cliff and large 

 quantities of the material fall down in spring. Unfortunately this 

 year it was carted away before it had been examined. 



LAKE SHORE DRIFT, WINONA. 



M}' old friend and fellow-worker, the late President of the 

 Geological Section (A. E. Walker), called my attention to a well- 

 preserved tail of a lower Silurian trilobite, AsapJuis PlatycepJiahis, 

 which he had just extracted from a slab of shingle embedded in 

 glacial clay, which underlies the ancient lake beach, now known as 

 the Burlington Heights. This discovery was recalled to recollec- 

 tion by noticing some glaciated limestone shingle in the lower part 

 of the drift a little above the lake level near Winona Park. Some 

 others which were lying loose on the strand presented a similar ap- 

 pearance, so it seemed quite natural to conclude that many of the 

 fossiliferous slabs were originally combed out of the clay there.
