clay is absent at the brow of the escarpment, the great protec- 
ing agent of the banks further inward. I believe a colony 
existed there of that rare Lingula, ‘‘ Z. /ngerus Spencer.” I 
succeeded in extracting one during the collecting season in good 
preservation and fractured two others. They were not seen z7 
situ, but probably came from a middle layer in the Niagara 
chert. It is said the owner has lately permitted the corporation 
to use the upper beds for macadamizing purposes. 
GLACIATED CHERT FOSSILS. 
The writer secured an unusual number of sponges and 
various organic remains during the past season. Since his 
return from Winona several fields along the corporation drain 
had been ploughed up and planted with Indian corn, and in con- 
sequence of a long-spell of dry weather the crops failed. Where 
not planted in rows, in some places, particularly near the drain 
and school-house on the Barton road a little beyond the Went- 
worth Hotel, the conditions were exceedingly favorable for 
collecting, although more weathered chert, flint-flakes, etc., 
appeared on the surface than was previously noticed. Perhaps 
not many new sponges or sections were discovered, but the ones 
we forwarded to the British Museum were in good preservation, 
and the same may be said of all specimens forwarded to England 
from this locality. The lands near the road at the top of the 
escarpment, a little beyond the city reservoir, were rather disap- 
pointing, although a few good sponge sections were obtained 
there. Some fields have been closely searched for years by fossil 
hunters, but in others the timber has only been lately removed, 
and insufficient time has elapsed for the weathering process to 
remove the outer covering which conceals the Spongide. The 
swampy part of a field not far from the outlet of the corporation 
drain, displays quite a number of flint-flakes, which hold very 
few fossils. 
The Barton Niagara shales overlying the chert may be 
recognized in the rising ground a little to the west of the 
corporation drain.. The ridge has been under grass for many 
years, but formerly held several sponges, corals, lingulide,
