ciated with the general Rockery, and judiciously managed, are pleasing. Two 

 or throe groups of this kind, formed on the top of an extensive Rockery, 

 would give variety to the general outline, the effect of which would also be 

 heightened by mingling with them a few conical plants, such as junipers, 

 savins, Irish yews, &c. 



Conical Rockeries may be formed, or imitated, by grouping a number of 

 large and small pointed stones, many of which should be placed as closely 

 together as possible, nearly perpendicular, and of different heights. Then, 

 in order that the divisions between these stones may not appear too great, 

 smaller ones should be placed amongst them, so as to harmonize with the 

 large ones, and, afterwards, scraplings and soil should be thrown amongst 

 them, so as to prevent the base of the stones being seen at all, as that would 

 destroy the appearance of their starting from a solid bed below. Lesser cones 

 may also be formed in the same way, near to the principal ones, so as to form 

 groups of cones ; but the whole must appear to break out of the knoll, or 

 artificial mound, that the idea may be given of time having wasted the softer 

 material, and left the harder in its present state. In some cases, cement is 

 used in fixing cones and other parts of rock-work, with a view to produce a 

 natural effect, which is well carried out in some of the rocks at Chatsworth. 



An old quarry, out of use for supplying stones, sometimes affords a fine 

 opportunity for forming a Rock Garden. The various-sized knolls or hillocks 

 produced by the refuse in working the quarry, will, in most cases, give the 

 variety of undulation wanted. The whole of some of these hillocks will 

 require to represent an entire mass of rock; others partly for rock and 

 partly for planting; and others, again, for being principally covered with 

 heath, whin brooms, honeysuckle, ivy, &c, with rude stones here and there 

 protruding from amongst them. Against some of the larger mounds, perpen- 

 dicular rock-work should be raised, to correspond as much as art will admit, 

 and to harmonize with the principal rocky face left by the quarry-men. 

 Perhaps in some parts the latter may want a little assistance to produce 

 various flats or tables, projections, recesses, chasms, &c. Walks or tracks 

 must be formed to wind naturally amongst the hillocks, sometimes advancing 

 towards the principal rock, and at other times receding from it. These should 

 be made dry, and instead of gravel should be covered with chippings of 

 stone. Their breadth should appear unequal, and irregularly margined with
