leads me to state that 3A0U should by all means collect at 
least a half-dosen good specimens of adult mongoose, so that 
v/e may be perfectly sure as to the species introduced into 
Porto Rico. Please ascertain also vdien the mongoose was intro- 
duced into the island and whence the individuals transplanted 
were derived, 
Mr. Bailey tells me that the bats you have sent in were 
both valuable and interesting, especially as you secured a 
number of species. 
There is a ma,tter of some in^ortance which I wish you 
would attend to when opportunity affords. We very much need 
a couple of specimens (adult, if possible) of the great blue 
heron found in Porto Rico. Very likely you are not in the 
locality frequented by these birds, but v/hen opportunities 
arise please secure a couple, salt them, and send them in at 
once to be mde up here, as v/e desire to have them as soon as 
possible. 
Trusting that you will have good health and continue your 
successful work, I remain 
Very truly yours.
