“Flowers of the Field,” the best cheap introduc- 
tion to systematic botany which has yet appeared. 
Trained, and all but self-trained, ike Mr. Hugh 
Miller, in a remote and narrow field of observation, 
Mr. Johns has developed himself into one of our 
most acute and persevering botanists, and has added 
many a new treasure to the Flora of these isles; and 
one person, at least, owes him a deep debt of gra- 
titude for first lessons in scientific accuracy and 
patience,—lessons taught, not dully and dryly at the 
book and desk, but livingly and genially, in adven- 
turous rambles over the bleak cliffs and ferny woods 
of the wild Atlantic shore,— 
‘* Where the old fable of the guarded mount 
Looks toward Namancos and Bayona’s hold.” 
Mr. Henfrey’s “Rudiments of Botany” might accom- 
pany Mr. Johns’s books. Mr. Babington’s “ Manual 
of British Botany ” is also most compact and highly 
finished, and seems the best work which I know of 
from which a student somewhat advanced in English 
botany can verify species; while for ferns, Moore’s 
“Handbook” is probably the best for beginners,
