writing upon it sufficiently explain its object and mode of 
being used for drawing sections. The copper plate which I 
had made for my own use, is at the service of any member of 
this Society, and I have ascertained from the engraver, Mr. 
Collard, of Newcastle-on-Tyne, that impressions can be sent 
by post, pre-paid, at the cost of 10s. a hundred. By sending 
a post-office order, therefore, for 5s., 10s., or 15s., to Mr. 
Collard, 50, 100, or 150 copies of this lesser chart may be 
had at any place by post, without further expense. Contri- 
butions of accurate sections, in this or any other convenient 
form, will, in time, become a valuable local record, and tend 
to familiarize the public with those geological details, which, 
on a larger scale, are sought to be obtained from railway 
cuttings, and, on a still larger scale, from accurate records of 
raining operations. The charts which I have described, 
simplify the process and secure uniformity ; the one can be 
had, through the munificence of the British Association, 
gratuitously, and the other for the mere cost of paper and 
printing ; and, I doubt not, that if the opinions of the able 
and intelligent members of this Society coincide with those 
expressed in this paper, that at future meetings of this 
Society, and at the next meeting of the British Association, 
many of these engraved charts will picture forth with geome- 
trical accuracy and graphic colouring, the important and 
highly interesting details of the geology of the midland 
districts of England, to be studied by the agriculturist, the 
miner, the engineer, the geologist, and by all who recognise 
in a correct knowledge of subterranean wealth, the strong 
foundations and only lasting means of preserving, what the 
late President of the Geological Society has justly termed, 
our country's exalted position among the kingdoms of the 
earth." T. S.
