another cause of extermination indicated thus :—“ Often a 
master with his pupils or a professor with his students, 
making a botanical excursion, arrives at a habitat of rare 
plants. Each one helps himself freely, even profusely, 
without thinking that in this fashion the species will rapidly 
disappear.” And again, referring to the researches of the 
ordinary collector: “Many botanists are in the habit of 
taking too large a number of specimens of rare plants, 
without reflecting on the consequences of this act of 
Vandalism.” 
Finally, the operation of Exchange Clubs is illustrated 
by the experience of a member of the same society who 
applied to one of them for assistance in filling up certain 
gaps in his herbarium, and was in reply asked to enter into 
an active exchange of specimens. A long list of the rarest 
plants was sent to him, with the request to supply “100 
fine plants with roots,” “ as much as possible, whole plants 
with buds, fruit, &c.,” while of several species he was asked 
to forward “ a cart-load.” Putting the “cart-loads” on one
