Of several hundred known kinds not more than 50 are 

 in cultivation, and a dozen species will cover those deserv 

 ing of greenhouse culture but these few are gems All 

 of this most important section thrive m a winter tem

 the freezing point is sufficient They do not like heat

a more beautiful plant than A. puhescens, with Its 

 slightly drooping, yellow racemes. It deserves a fa- 

 vored place in every cool conservatory. The Acacias are 

 of easy culture. If planted permanently In the border, 

 provision for drainage should be made. A good, coarse, 

 turfy loam, of not too heavy texture, is all they want, 

 with the addition of a fifth part of leaf -mold or well- 

 rotteil spent hops. Few of our greenhouse pests trouble
