68 THE HAMILTON ASSOCIATION. 
specimen obtained from the lower Barton beds was a short 
distance beyond the rock-cutting on the old Hamilton & Erie 
line, where a small stream (dry in summer) crosses the road and 
which forms a little way down the small ‘‘Horse Shoe Falls.’’ 
Later on quite a number were discovered on the rising slope, 
south of the corporation drain at the base where the shales 
overlie the chert beds. ‘The fields have not been ploughed up 
for several years, but imany sponges were obtained 
formerly from the ridge by the late Mr. Turnbull and the 
writer. Other organic remains have also been found there Posz- 
donommya corresponding with one beyond the rock-cutting near 
Albion Mills (common) Favosites, a fine Lingula larger but 
not unlike Lingula teeniola (Hall), several specimens of Rhyn- 
chonella ‘Tennesseensis (Roemer) may be obtained also from 
this locality. 
The fields near the mouth of the corporation drain 
towards Albion Mills at the brow of the escarpment, which were 
found to be so rich in sections of sponges during the two pre- 
vious collecting seasons, yielded very few recently. This may 
be attributed to the nature of the crops (clover, etc.) and the 
small orchard near the Barton and Glanford stone road, from 
which the fine sponge (now in the British Museum) was 
obtained at an early part of the year, proved exceedingly dis- 
appointing later on ; indeed the same may be said of the one a 
little higher up at the other side of the road. It merely fur- 
nished an indifferently preserved Astylospongia and a few 
sections. This may be owing to its close examination for 
many years since cultivation. The surface soil is thin there 
and the Erie clay is absent. As regards the aspect of the 
ground nothing unfavorable was noticed, and it was suff- 
ciently uncovered to enable one to see the fossils if they were 
to be had at all. 
It may be within the recollection of members of our 
Section that at one of our meetings last year a brief discussion 
arose regarding parasites attached to sponges. The plain 
globular dense-spiculed one in the Niagara chert beds had appa- 
rently some attraction above others for a Bryozoon (Lichenalia)
