This map, the first sketch towards Smith's great map of 1815, is 
hung in the library of the Geological Society. 
SMITH, MS. 1801. 
Among the papers left behind by Smith was one dated 1801, 
which was probably the work Smith had in mind when issuing his 
first prospectus in 1800. It is entitled : " Plan of the Work : To be 
divided into Two Parts." The First of which should treat of the struc- 
ture of the earth, or general disposition of the most remarkable knmvn 
strata, collected from the best authorities, and arranged according 
to the order discovered in England, and the Second should enter into 
the particulars of each stratum, with the fossils and minerals that have 
hitherto been discovered, with their connection and dependence one 
upon another. Though it is impossible for the labours of an individual 
ever to acomplish a thousandth part of what is proposed by this section ; 
yet when a system is established which has Nature for its prototype, 
every one will be enabled to contribute his mite, and carry it on from 
time to time, till after ages may get a tolerable description of the 
habitable world. 
" Many sections of the strata, in different directions, will be 
necessary to show their various inclinations. In the general section, 
each principal stratum should be numbered with progressive numbers, 
beginning at the eastern strata of the kingdom ; or, till that can be 
accurately ascertained, at some stratum that forms a grand feature 
therein. As for instance, the chalk which I would call No. 1 ; and those 
lesser strata which are contained within it, or generally attached to it, 
or form any subdivisions therein, I would call la, lb, Ic, &c. If any 
thin stratum should be omitted, or a new one discovered, it mav be 
brought into those numbers, by making it laa, &c. 
" After the general section of a country or district, should follow 
•a large section of each stratum, with its concomitant small strata ; 
with drawings and descriptions of such peculiarities as the principal 
stratum, or those connected with it, are found to contain ; whether 
the exuviae of marine animals, vegetable impressions, or fossil wood, 
coal, and metal of every description.
