WILLIAM smith: HIS MAPS AND MEMOIRS 
" No. 9* This Stratum here obscured and imperfect produces 
in the Vale of W ardour a few Miles Northward the fine Stone of 
ivhich Salishury Cathedral ivas huilt." 
" Extensive Sheep Pastures on the Downs — Water Meadows 
in the Valleys. 
''The River Stour ivhich rises at Stourton near Alfred's Tower 
runs parallel to the track of this Section from Stalhridge to Wimhorn 
Minster." . 
" Pipe Clay or Plastic Clay ivorJced extensively on the opposite 
side of Pool Harbour in the Isle of PurbecJc, where these Strata dip 
in an opposite direction and form the Southern side of the great 
Trough. 
" It occurs at Cary near Wareham, and has been sought for by 
various Trials on Pool Heath, &c., dc, some are said to have been 
experiments for Coal." 
The imprint is : " London : Published by John Gary, No. 181 
Strand, May 1st, 1819." It is reproduced on Plate XVI., fig. 2. 
Later Mr. Cary published two sectionsf similar in size to those 
described, viz. :— GEOLOGICAL VIEW OF THE MINING DISTRICT 
OF CORNWALL CORRESPONDING WITH THE MAP FROM 
CHASEWATER TO CAMBORNE shewing the Elevations of the 
Hills and the depths to which the Mines are extended, by R. 
Thomas. Falmouth, 1819." The imprint of this, however, reads : 
*' London : published by John Cary, No. 86, St. James's Street, 
July 1st, 1824." 
The other Chart is described as GEOLOGICAL SECTIONS IN 
ILLUSTRATION OF THE MAP OF THE MINING DISTRICT OF 
CORNWALL, BY RD. THOMAS, FALMOUTH, 1819." In this case 
however, the imprint, which for the first time is within the border, 
reads : " London ; Published by John Cary, No. 181 Strand, July 
1st, 1819."t 
* No. 9 = Portland Stone and Sand. 
t These two are bound up with Smith's Section in the copy in th« 
Library of the London Geological Society, and in my copy. 
J There may be some reason for this imprint, which is five years 
earlier than that of R. Thomas's other diagram, being within the 
border. It looks as though the original imprint, outside the border, 
had been cut off.
