All of these investigators returned north in excellent health, and in this 

 connection it is interesting to observe that since the pure-food law went into 

 effect we find that indigestion and other troubles have disappeared, although 

 these were formerly more or less prevalent where we must, as at Tortugas, 

 depend mainly upon canned foods for our supplies. 



Commodore William H. Beehler, U. S. N., commandant of the naval 

 station at Key West, has been unfailing in his generous interest in the station 

 and has, as in the past, been ever ready to offer aid to us upon all occasions.
