" Build the walls of good-faced bricks, a brick and a half 

 thick, or of stone, whichever can be obtained the cheapest. 

 Six feet above the ground-level lay a layer of flagstones 

 8 inches wider than the thickness of the walls. The above 

 said flagstones to be 3 inches thick, to face even with the 

 exterior, but to project 8 inches into the interior of the 

 house at both ends and both sides (the door excepted), on 

 which two hot- water pipes i.e., a flow and return, are to 

 be fixed hereafter. Build another foot more wall upon the 

 flagstones, which raises the walls to rather more than 7 feet, 

 the height desired. 



" The ground plan given is merely to point out to those 

 who have not seen anything of the kind, or have not the eye 

 to draw from certain given details any correct idea of the 

 effect intended to be produced by the carrying-out of the 

 description. 



" It is presumed that the site for the house is situated so 

 as to be low enough for the water that supplies the fountain, 

 &c., to be conveyed in iron pipes without having to make a 

 reservoir especially for the purpose. The reservoir should 

 not be less than 10 feet above the ground-level of the house. 

 [For the details of the plan see the following page.] 



" We will now proceed with the construction of the rock- 

 work. The material throughout should consist of massive 

 fragments of freestone rock that have been exposed to the 

 weather for a considerable length of time, and, if possible, 

 out of a wood, or where the sun's rays have been but faint. 

 We prefer such from experience, of which we have had 

 a little. Old, shaded stones are frequently covered with 

 Mosses when they are brought from the woods, &c., and on 

 some that we got about a year ago out of the woods in this 

 locality, are thousands of seedling Ferns of no less than
