Although it contains few fossils the succeeding Upper Green 

 Clinton Band is of much interest. Evidently deposited in a shallow- 

 sea, the sandstones pointing to a shore line display the ripple marks 

 left by the waves on the Silurian beach, and the burrows of an 

 annelid closely related to a modern lob-worm ; they are vertical and 

 in pairs. Nicholson's Planolites or errant worm occurs here also. 

 The few plants are ill preserved ; one of them had a bulbous root. 

 While the sea bottom was undergoing depression, previous to the 

 deposition of the limestones, a fucoid, colored black in the green 

 shales, put in an appearance. The stems are fluted like the 

 Cambrian Eophyton, or a striated fucoid from the lower red 

 sandstone, figured by Hugh Miller. The branches appear to be of 

 the same thickness throughout. When the limestone rests on the 

 shales, the base bed of the Niagara proper, according to all Canadian 

 geologists, it has caught up and attached, scarcely incorporated, a 

 portion of the clay underneath. On splitting this the plant is seen, 

 but it survived the submergence of the clay deposit, for I have 

 traced it even in the interior of the lower building block as well as 

 in others superimposed. 



So recently as the 6th of November last, I noticed in the 

 quarry adjoining Mr. Colbeck's place, on a limestone block, the 

 remains or impression of a sea weed differmg from others found 

 here If I could succeed in extracting it uninjured for Sir Wm. 

 Dftwson it might prove of much interest. It is on such ill massive 

 layer that I think it may be rather difficult to do so. Dana 

 remarks that limestones seldom contain Plant Remains. It is not 

 so in Canada^ however true it may be as regards the States. The 

 limestones at Macdonald's Cove, on the north shore of Anticosti, 

 contain detached branches, perhaps of a Buthotrephis. I obtained 

 hundreds of specimens remarkably well preserved but never found 

 even a fragment of the main stem or conical root. Whether they 

 were distinct species or mere immaturities of the vegetable kingdom 

 I was unable to determine for my part. It was in the waterlime beds 

 at Rousseau's Creek above the Albion Mills that I discovered 

 the beautiful fucoid represented in Sir Wm. Dawson's work on Fossil 

 Plants as an undoubted Silurian sea plant. The layers in question 

 hold others also, which for the present must remain undetermined. 

 They vary considerably as regards the thickness of the stems or 

 branches as well as in lesser particulars. I think it probable that
