succeeded, however, in securing a few specimens of a minute Alga, 
which, I am inclined to believe, may prove to be a new species. 
Many years ago, slabs were found containing this fossil, rather 
poorly preserved, in the shale. On submitting them for examin- 
ation to a geological friend, he remarked, ‘‘It is a matter difficult 
to determine—corals, perhaps.’’ I rather imagined it represent- 
ed generations of small Silurian Sea Plants of the Niagara age, 
as no hard portion remained, as would be the ease in corals. 
On returning from the Albion Mills waterlime beds, I noticed . 
a farming friend of mine busily engaged in cutting down his 
Indian corn crop, near the outlet of the corporation drain. The 
field in question presented some clear spaces, where I may obtain 
at least a few sponge sections, perhaps. I thought the result 
exceeded my expectations. In addition to several fine sections, 
I brought back two or three complete sponges. All, however, 
were known to me previously. Among the sections discovered 
were some few rare ones, now ditficult to obtain nearer Hamilton. 
I am perfectly satisfied we have not yet secured a complete 
series of the Niagara sponges, which are only found in this local- 
ity. I did not see the collection the late President sent to pro- 
fessors in Germany. I remember he was in possession of examples 
of the Spreading Aulocopina, one of several species of the family. 
I pointed out a field to him which furnished me with sections, 
pointing to a number which possessed a large circular osculum, 
encircled in a regular ring of smaller ones. Neither of us, I think, 
discovered the entire sponge. 
When the corporation handed back the Webber and Han- 
cock quarries, there remained in the former a portion of the blue 
building beds held by the proprietor. As these were not far from 
the brow of the escarpment (which was found to have many 
Graptolites there in former years), I considered I could count 
on obtaining some more when the workmen reached the part in 
question, which they were fast approaching, In this F was 
greatly disappointed. However, a considerable amount of build- 
ing material was removed during my absence at Winona, and, 
as many of the Graptolites are smal! and not easily recognized by ~
