VIX. VAPOR RUB Another helpful remedy is to have a couple of iars 
of Vix Vapor Rub. This is very helpful in the country where they have Bete 
Rouge or Chiggers as they are improperly called. The Vix Vapor Rub is very 
soothing and will stop the itching of the Bete Rouge when trying to sleep at 
night. It is also good to rub about the, throat and chest in the treatment 
of colds as a counter irritant. 
D.D.T. In regard to insecticides I have usually found it desirable 
+o carry a pound can of the technical D.D.T. which may be added to plain kerosene 
to make up a spray. This saves carrying bulky fluids. The proportions are one 
pound of D.D.T. powder to three gallons of kerosene, which gives a 5 % solution 
of D.D.T. 
EMPERIN COMPOUND You should also carry some Emperin Compound tablets 
which contain asperin, caffein and phenacetin. These are very useful in the 
treatment of colds and also to relieve pain. Two tablets should be taken every 
four hours. They are put out by Burroughs and Welcome. It would be well to cariy 
some compressed cotton and gauze also manufactured by Burroughs and Welcome. This 
saves space. 
INSTRUMENTS You should have a pair of scissors, forceps and a. 
\ Bard Parker scapel and handle and a few ex+ra blades. They are handy if you 
✓"fthave to open an abscess. Always remember to pack the wound with gauze after 
'** the abscess is opened, keeping a drain in it until the wound is free of pus. 
ANALGESIA Analgesic packing, such as dentists have, is very 
useful. A gummy substance containing creosote is sometimes used. It can 
be packed into a cavity and relieves pain. Probably your local dentist could 
supply you with this. 
I believe that all of these drugs may be purchased at Eimer and 
Amend’s Drug Company, New York City. 
If you carry a supply of the above mentioned things, 1 believe you 
will find that you can travel quite safely if you will be sure to observe 
the necessary precautions as I know you always do. 
It was a great privilege to he with you again on Monday evening 
and I only wish that I could be in the field with you on one of your trips.
