as it approaches the Rockery. The extreme outline of the plot allotted for the 

 Rockery is the most proper situation for the principal body of rock, because 

 the bank forms proper backing and support for the stones, and gives the idea 

 of a natural rock protruding from it, as we generally find it in natural rocky 

 ground. 



Further, sometimes in sinking the lower parts of the given plot, and 

 adding to the swells, when they are not sufficient of themselves, an opportunity 

 is afforded of making rocky groups, in some cases to occupy the whole of 

 the knoll, and in others only part. 



The principal tiling to be avoided in forming artificial rockwork is the 

 appearance of a mere stone-heap, such as we too frequently see. The mass of 

 the rock should invariably commence with the largest stones at the bottom, 

 allowing the bottom of the stone to be just sufficiently covered, so that the 

 depth of the rock cannot be detected nor even imagined. In order that the 

 rock may appear massive and of importance, the principal stones should be 

 of two or three, or even more, tons weight, and should gradually be diminished 

 to about half a ton, and occasionally of less size, even to a few stones weight. 

 The kind of stones most to be preferred are those which have become grey 

 with lichen or moss, by exposure to the weather ; but when these are not to 

 be had easily, quarry stones may be resorted to, which in time will assume a 

 natural hue. In placing these, they should be bedded as much as possible in 



seams, some parts appear-
