450 Jopling's Isometrical Perspective, 



highly gratified by the manner in which it has been received 

 by the public ; and though it is so cheap that it will probably 

 not pay its expenses for some years, yet it delights us to 

 think of the good which, in the mean time, it will do, not only 

 in Britain, but in America. 



Jojpling, Joseph, Esq., Architect : The Practice of Isometrical 

 Perspective. Part I. price l5.; to be completed in four 

 Parts. London, 1833. 



Isometrical perspective is by far the most useful kind for 

 the landscape-gardener and garden architect; because it 

 alone, of all the different manners of drawing, contains the 

 true principle of drawing maps and plans of grounds and 

 buildings, so as to show the heights and shapes of the objects. 

 The young gardener, who does not understand isometrical 

 perspective (which we have briefly explained in Vol. VI. 

 p. 351. fig. 11.), we hold to be unfit for acting either 

 as a delineator of plans for laying out pleasure grounds, 

 or for building the walls of kitchen-gardens, or erecting 

 hot-houses. We, therefore, strongly recommend this little 

 work to all such of our young readers as are ambitious 

 of rising in their profession. We would also strongly 

 recommend Mr. Jopling to render his work, in a peculiar 

 manner, fitting for the gardener, land-surveyor, and mine- 

 ralogical surveyor, by showing the application of isometrical 

 perspective to rural scenery, and imagining plans and sec- 

 tions of mineral districts. At a late meeting of the Society 

 of Civil Engineers, at which we were present, an admirable 

 map of a mineral district in Northumberland, with the sec- 

 tions, in different directions, of all the various strata, was 

 exhibited and explained ; expressly for the purpose of show- 

 ing how well adapted isometrical perspective is for this 

 description of delineation. Its application to garden scenery 

 we have shown in our Illustrations of Landscape-Gardening, 

 and to farm buildings in our ILncyclopcedia of Architecture. 

 Its application to machines and various objects may be seen 

 in the Mechanics' Magazi?ie, one of the cheapest and best 

 books that a gardener can take in.
