rounded pieces of till or boulder clay of lenticular and sphe- 
rical shapes, varying in size from one to three inches 
through their major axes. The specimens on the table are 
three taken out of the cutting by myself, and are a fair 
sample of the average boulders. 
There is not a section of the whole of the drift deposits 
at Moss Bank, but at the Manchester Workhouse, about 
quarter of a mile distant, the following deposits occur, the 
second being the equivalent of No. 1 in the preceding sec- 
tion :

To my knowledge no instance of boulders of clay in drift 
beds has been published. Many years since, when, obser- 
ving the fine cliffs of till at Blackpool, I noticed how the 
waves rounded the stones from that deposit which fell down 
on the shore, and I also saw a few of the pieces of clay 
rounded as well. In the last December number of the 
Geological Magazine is a description of some clay boulders 
by Mr. T. Melland Reade, F.G $., lately observed by him on 
the Crosby shore near the river Alt. After describing a 
trench about 50 yards long, 5 feet wide and 2 feet deep, cut 
in the blue clay which underlies the peat and forest bed,* 
and which formerly had only a deposit of sand at the bot-
