sheep, which make the pasture so different from the meadow flora 
by continual grazing. The human species causes a little more

No Hake distinetion exists in reality, nor can one be made in botany 
without violating the first principle of true observation, namely, 
that “ what is found is natural.’ 
Indirectly H. C. Watson tried to simplify the riddle, pas the 
mesh of the net he used for the purpose was too wide to catch all 
the fragments of em ndsbatie required for a satisfactory nen 
tion e showed us the way, however, 4 he did not arrive at ns 
goa al, or go vty far on the road himself. All honour to him 
Much though I admire his patient aitey and methods, he 
eed fails in getting at the truth he was indirectly seeking, 
despite hi a eee egos logicality. The terminology he 
employs is defective, for it is unusually difficult in applica- 
on. The pons erat r of his method 
per se, as if they had a mind of their own, as natives, denizens, 
eee or casuals, eather than in their varied relation to 
e great disturber. The astonishing thing is that such a 
time should have elapsed without a more natural method being 
suggested. 
We must put the Watsonian distinctions from our mind, and 
turn to a more eneresing method. Let us try arranging all the 
species in any flora we know well under the following heads— 
remembering, as ‘ do so, in England there is nothing natural if 
you exclude human influence, and that without accurate rock-soil 
notes exact classing is almost impossible.
