In preparing soil, therefore, for allCactuses (except EpiphiflUmi and Rhipsalis, which will betreated separately), a good, rather stiff loam, with plentyof grass fibre in it, should form the principal ingredient,sand and, if obtainable, small brick rubble being added—one part of each of the latter to six parts of the brick rubble should be pounded up so that the largestpieces are about the size of Hazel-nuts. Lime-rubbish, ,old plaster from buildings, &c., is sometimes recommendedfor Cactuses, but it does not appear to be of any useexcept as At Kew its use has been discontinued,and it is now generally condemned by all good course, the idea that lime was beneficial to Cactuses.

The conditions in which plants grow naturallyare what we usually try to imitate for their cultivationartificially. At all events, such is supposed to betheoretically right, however difficult it may be found inpractice. In Cactuses, however, we have plants for whichspecial conditions are necessary; and, as regards soil,whether we are guided by nature or by gardeningexperience, we are led to conclude that almost all ofthem thrive only when planted in one kind, that soil beingprincipally loam.
