Mr. Hull, in his communication, read at the last 
meeting of the Society, divided the higher drift deposits 
into (in descending order): — “(1) Upper Boulder Clay; 
(2) Middle Sand and Gravel ; and (3) Lower Boulder Clay. 
The Nos. 2 and 3 had been described by the President 
as also a lower bed of sand and gravel, of whose existence 
lie (Mr. Hull) had considerable doubts, and considered it 
as merely accidental.” Now, in his (the President’s) 
Paper on the Drift of Manchester, 11 sections of wells 
and bores are given, and in ten of those the lower sand and 
gravel had been met with ; thus shewing that it can scarcely 
be considered as merely accidental, as Mr. Hull states. In 
many other sections since examined in Lancashire, this 
deposit has also been found under the till. With regard to 
the upper bed of boulder clay, Mr. Hull stated that he (the 
President) had alluded to it, but Mr. Hull considered it to 
be quite as important as the lower, both in thickness and 
area . 
The old term “ till ” is as good as that of boulder clay, and 
as it has been loim used there is not much use in chanffinsr 
it. During the last twenty years he had collected many 
facts, which he intended to publish when he had completed 
his collection, but these did not show one bed of clay or 
marl which could be called upper boulder clay, but several ; 
in fact there were numerous intercalations of it in the sand 
and gravel, one of which he had seen occurring at Kersall 
Moor entirely surrounded by sand. To show the complexity 
of these deposits, and the difficulty of reducing them 
to two, he gave two sections, one near Hyde and the 
other at Outwood, where the following strata were met 
with : —
