Formations," thus observes: "The upper limit of Halysites 

 Catenulatus, so far as known in New York, is in the Niagara 

 limestone." 



Before reaching Jacquet River we observed a point with 

 singular looking rocks : on closer examination thev were found to 

 consist of conglomerates, very much resembling the new red sand- 

 stone conglomerates of Nova Scotia. These repetitions of post 

 Silurian rocks seemed somewhat perplexing, occurring in a 

 supposed Silurian region. It was only afterwards that I found 

 them to be carboniferous. We crossed the mountain and reached 

 Dalhousie without understanding the character of the rocks which 

 formed the elevation. We then crossed the Restigouche and landed 

 in the province of Quebec, just in time to examine the rocks on 

 the shore by twilight. We had landed among sandstones. In 

 these I found the part of a fossil fern. I walked along the shore 

 and examined the junction of the sandstones with the conglome- 

 rates of new red sandstone? apart by moonlight. I took note of an 

 enormous mass of the conglomerate which had recently fallen. I 

 retraced my steps to our boat and we recrossed to Dalhousie. Mr. 

 Walker promised to take me to a locality where he understood 

 that curious rocks were to be found. 



Early in the morning (5 o'clock) we were found in our boat of 

 the previous evening. We rounded the Island and landed some- 

 where at Cape Bon-ami. We had passed slate which seemed to 

 be sandstone. The rocks which we first met were Traps. 1 had 

 come expecting to find fossils and was rather disappointed ; I could 

 never expect to find fossils in Trap rocks. However, the rocks 

 themselves were a study. Their rugged form and arched gate- 

 way ; their columnar and amygdaloidal structure, were sufficiently 

 interesting. Their minerals too, veins and amygdals of agate and 

 calcites, and geodes of quartz crystal, merited attention. Beyond 

 the first Trap, in the cove, we unexpectedly found what we most 

 wanted — Silurian strata perfect coral reefs. Favosites gothlan- 

 dica? in abundance, and Oyathophylla, Strophomena depressa, 

 Atrypa reticularis, Athyrus nitida, Orthoceras, Crinoidea. 



My perplexity was great, and also regrets at having before me
