left the State for some years. Asa systematic botanist Mr. Greene 
began to write in the year 1880, and his first contribution to the 
literature of Californian botany was made in 188r. 
Mr. Greene is most evidently of opinion that any comparison 
between his work and that of Dr. Gray must be immensely to 
the disadvantage of the latter, but there are a few things it 
might be well for him to remember. One of these is, that Dr. 
Gray’s work on Western botany is essentially that of a pioneer, 
that he worked always under pressure, and that the great pre- 
liminary work accomplished by him has enabled a swarm of 
others without half his mental grasp to labor acceptably in more 
restricted fields, and sometimes, as in the case of Mr. Greene, to 
wound the kind hand which led their first weak footsteps in the 
determination of plants. 
Dr. Gray made many errors, as must be the fate of any 
botanist so situated, but be never hesitated to admit and correct 
them, in which characteristic he differs strikingly from Mr. 
Greene, and he was thoroughly incapable of ‘‘covering the 
nakedness of his own incapacity with the mantle of another's cul- 
pability ’ a process in which it is to be hoped Mr. Greene will 
have few imitators. K. B.
