the principal strata, which are enumerated therein in their order, 

 from chalk downwards to coal ; which order of the English 

 strata had not previously been ascertained and published by any 

 one ; or the fact known that London is situated on almost the 

 highest of the British strata, which, in the following summer, 

 Mr. Smith ascertained. 



12. Having in the prospectus which Debrett printed and 

 circulated in 1801 (and of which also great numbers were distri- 

 buted while Mr. Smith was soliciting the names of subscribers 

 for the publication of his map and memoir) * set forth, very fully, 

 what were the objects and advantages to various classes of the 

 community as well as to science, which would result from the 

 diffusion of the knowledge regarding the strata, which had then 

 recently been acquired. 



13. Having from the first commencement of his tracing and 

 mapping the British strata, in the most free and unreserved manner, 

 communicated to all the various mine, colliery, or quarry owners, 

 agents, workmen, &c. with whom he conversed on the spot, 

 throughout nearly the whole of England and Wales, and to scien- 

 tific men and others in general, t whatever they wished to ask re- 

 garding the principles and process on which his investigations had 

 been commenced and carried on to the state in which his maps, 

 sections, and collection were then shown to them ; and as to the 

 general conclusions of every kind which he had drawn therefrom ; 

 and to Mr. John Farey in particular, the agent at Woburn for 

 the late Duke of Bedford's estates, at his Grace's particular 

 request (made before Mr. Farey had ever heard the name of 

 Mr. Smith mentioned), a full and particular course of instructions 

 was given in mineral surveying by Mr. Smith, at the time of 

 revising his map of the adjacent parts of Bedfordshire and Buck- 

 inghamshire. 



14. Having, at very considerable trouble and expense, brought 

 together and arranged a numerous collection of specimens of the 

 several English and Welsh strata, from numerous and distant 

 places (all of which were marked), on the range of each stratum, 

 as shown in his maps, and particularly of the organic remains 

 found imbedded in each of these several strata ; having rented 



Townsend's house in June, 1799; concerning which list, Mr. Farey published a 

 notice, on May 31, 1815, in (tie Philosophical Magazine, vol. xlv. p. 334; and in 

 August, of the same year, Mr. Smith published a copy of this original list, in the 

 *' Memoir" which accompanied his map, facing p. 8. The lale William Reynolds, 

 Esq. of Coalbrook Dale ; Mr. Tims. Bartley, of Bristol ; and others (see Phil. Mag. 

 vol. xxxviii. p. 338, note), received copies of this list, at secondhand, soon after 

 1799. 



• Monthly Magazine, July, 1801, vol. xi. p. 525. 



+ Foi several years after 1800, Mr. Smith made a point of attending nearly all 

 the public agricultural exhibitions of the Bath Society ; of Mr. Coke, at Holkham; 

 of the Duke of Bedford at Woburn ; and of Lord Somervilleand the Smithfield Club, 

 in London; and there publicly hum' up and showed his map of the strata to many 

 hundreds of intelligent persons ; which fact has very often been recorded in the 

 newspaper account* of the proceedings of these meetings. See the Star, June 21, 

 1804; Phil. Mag. vol. xxxv. p. 114, &c.
