the drainage after the recession of the ice. He thought that 
the barrier of drift in the old valley represented the moraine 
laid down by the ice. 
A discussion followed, in which Messrs. W. Whitaker, F.R.S., 
H. Preston, F.G.S., and others took part. Alderman Creswell 
expressed the satisfaction of the members of the local society 
at having been invited to be present, and moved a vote of thanks 
to the Mayor, as Chairman of the Technical Committee, for 
the use of the room. Mr. Culpin proposed a vote of thanks 
to the Louth Antiquarian and Naturalists' Society, coupling it 
with the name of Mr. C. S. Carter, their secretary, for their kind 
attention and courteous hospitality. Mr. C. S. Carter, in reply- 
ing, said that the local society had received a valuable stimulus. 
They had come to recognise that they had a geology exclusively 
their own. 
Prof. Kendall, in answer to Mr. Preston, said that all they 
knew of ancient glaciation seemed to show that a glacier did 
not throw down its debris all in a heap. It carried its rock 
rubbish chiefly in its lower layers, and a process of shearing 
accompanied the advance. There was no evidence that the 
Wolds ever supported glaciers of their own. 
On Tuesday, April 27th, the geologists explored the country 
between Louth and Swaby, with a view to an examination of 
the glacial features of the district. In this tract of country 
are numbers of lake channels, running in series across the country 
in lines, which would appear to mark stages in the recession of 
tlie ice, and examples of two types of lake-channels were seen. 
One type has been left dry and deserted on the recession of the 
ice, but the other had been cut so deeply as to become the per- 
manent line of post-glacial drainage. Driving to Tathwell, 
the Eskers sand-pit and a chalk-pit were visited, and the country 
near Bulty Hills was investigated. Near Orgarth Hill Farm 
a difficult problem in the formation of tlie valleys presented 
itself — described by Prof. Kendall as one of the most difficult in 
the Louth area, the ends of the valley appearing to have drained 
in opposite directions. The party walked through the beautiful 
channel of Haugham Bottoms, and thence to Burwell and Walms-
