species being arranged according to their systematic sequence. I 
have now had the collection under constant inspection for three 
years, and have made a catalogue of the species, classifying them 
in three groups, according to their power of survival under the 
conditions as explained. * * *

Poputar Borany.—It is a matter of regret that the eminent 
men who have devoted their lives to botany in this country, have

doubt some of the things now donewould have been left undone, 
yet we are confident that it would nevertheless have been muc 
better for the science of botany. There is a duty which every
