The conservative pit is also the proper habi- 

 tation, during winter, for the ever-flowering tree 

 carnations, the more delicate varieties of hybrid 

 Phloxes; Antirrhinums; chrysanthemums; and 

 true Cape geraniums — a section of that extensive 

 order, long neglected, but of late brought again 

 into popular favour. Some of them, as anemo- 

 nseflorum, shed their leaves annually — others, 

 as echinatum, make short stubby shoots, and 

 become nearly or wholly deciduous duringwinter, 

 and hence are enabled to withstand several 

 degrees of frost with impunity.

§ 13. — CONSERVATIVE WALL AND BOR- 

 DER, PROTECTION OF HALF-HARDY 

 TREES AND PLANTS, &C. 



The conservative wall and border may be 

 denominated the connecting link between the 

 greenhouse, cold pit, and the open unprotected 

 border. The plants which furnish them are 

 such as will not withstand the cold of our win- 

 ters without some partial protection, and yet 

 will grow and flower profusely during the sum- 

 mer and autumnal months. The situation should 

 be dry, exposed to the sun, and well sheltered, 

 but not shaded by trees. The soil should be 

 rather poor than otherwise, resting on a dry 

 bottom, and the wall constructed so that a 

 temporary covering may be applied during win- 

 ter. For construction, tide vol. i. p. 101. The 

 best protection is unquestionably glass, because, 

 unlike all other material employed for a like 

 purpose, it admits light, and to a considerable 

 extent heat also, at least during the day. There 

 are, however, other kinds of protection, which, 

 although incapable of admitting light to the 

 subjects covered, are valuable on account of 

 their non-conducting properties. Of these we 

 may mention the well-known garden bast-mat, 

 canvass, bunting, netting, oiled paper set in 

 frames, branches of trees, fronds of fern, straw 

 ropes, wisps of straw, reed matting, wooden and 

 felt shutters, and the more recently applied 

 Frigi Domo, a canvass made of prepared hair 

 and wool, a perfect non-conductor both of heat 

 and cold. Three important principles ought-to 

 be observed in choosing and applying coverings 

 — namely, the exclusion of wet, preventing radia- 

 tion or escape of heat, and avoiding the exclu- 

 sion of light. Now the first of these is to be 

 effected by employing a material that is imper-
