stance of the kind has, I believe, ever been found on 

 the eastern shore of that river. 



The same may be observed on the west side of the 

 Susquehannah, from six to ten miles above tide water.* 



A similar fact is likewise mentioned by Mr. Bar- 

 tram, as existing on the shores of Broad river, which 

 discharges its waters into that of the Savanna. " The 

 waters at this place/' he says, " were still and shoal, 

 and flowed over a bed of gravel just beneath a rocky 

 rapid ; in this eddy shoal were a number of little gra- 

 velly pyramidal hills, whose summits rose almost to 

 the surface of the water, very artfully constructed by 

 a species of Cray fish, (cancer macrourus) which inha- 

 bited them."f 



These are not the only circumstances which Mr. C. 

 mentions, that are favourable to my views of this sub- 

 ject, exclusive of which, I could adduce numerous 

 other cases equally favourable to the opinion ; but one 

 or two of which, I shall mention in the present in- 

 stance. 



I have been informed by a gentleman of respectabi- 

 lity, who was a witness to the fact, that while the Bri- 

 tsih were employed in erecting a fort at Kingston, on 

 lake Ontario, in 1814, they discovered, at the depth of 

 fifteen feet below the surface, a variety of seeds lying 



* For this fact, I am indebted to Dr. R. W. Hall, who fur- 

 ther observes, " The fishes which form these mounds, are a specieg 

 of small mullet or gudgeon. They elevate the stones by suction, 

 and deposite them on the mound, as I have often seen."
