Geology of the Environs of Petersburg. 
I have given views in Plate 31, of this interesting and romantic 
glen, taken from the grounds of an old deserted country house on 
the right bank of the Tosna, the situation of which, placed on the 
summit of the rocky bank of the river, and surrounded with hang- 
ing woods of deciduous trees, abounding in rare and beautiful plants, 
which feather down to the water’s edge in every vacant space 
between the stony precipices, affords the wildest and most pictu- 
resque scenery to be met with in all the country round Petersburg ; 
and would not be misplaced in Wales or Austria. 
These, with the Pulcovca outlier, are the only places worth visit- 
ing on the Ingrian side of the Neva.* The Garelian side is still 
less fertile in interesting localities. The principal, however, are 
The hills and lakes of Toxova, which, though it does not offer 
much to the lover of geology, is yet worth visiting, as the most 
favourable specimen of the scenery of this side of the country. 
I may add Riabova and the banks of the river Okhta from the 
gorge of Copsala to its mouth. 
I flatter myself that this enumeration of the principal geological 
points, may be of use in saving many tedious hours of useless 
research to those who may hereafter visit the environs of Petersburg. 
In a country, the features of which, scarcely in any instance direct 
* It must be remembered that, however interesting some of the spots described may be 
in themselves, they are scattered over a very considerable tract of country. As places of 
minor interest, I may particularize Caporie, Lapoukhina, Gastilitzi, Ropsha, and the 
whole bank and gullies which intersect it between Strelna and Oranienbaum : also Pargola, 
and Coultoushy beyond the Neva, and the falls, as they are ridiculously termed, of the 
Neva itself. 
Among the manufactories, the iron works of Caterinhof, at four versts from Petersburg, 
those of Cesterbeck and Colpina, the former at twenty, the latter at twenty-four versts, 
distance : the paper works at Peterhof, and the cotton works of Alexandrovsky, deserve 
to be inspected.
