June,  1921.       )  a 
prevalence  and  dangers  of  pneumonia,  to  which  they  are  exposed, 
especially  in  the  highlands  of  Bolivia,  the  members  of  the  party 
have  been  provided  with  an  antipneumonia  vaccine,  which  should 
give  them  considerable  protection,  for  some  time  at  least.  If  it 
gives  them  a  moderate  protection  against  pneumonia  for  even  six 
or  eight  weeks,  this  will  carry  them  over  the  most  dangerous  period, 
i.  e.,  until  they  have  crossed  the  Andes  and  have  descended  from  the 
highlands  of  Bolivia  to  the  great  plains.  They  are  also  supplied  with 
various  insecticides  and  repellents  which  they  will  use  to  obtain  re- 
lief from  the  annoyance  of  incessant  attacks  of  hordes  of  insects. 
Through  Dr.  Rusby's  wide  experience  and  foresight,  all  the 
possible  needs  of  the  party  while  in  the  field  have  been  provided  for 
in  great  detail.  Among  the  supplies  are  large  quantities  of  food- 
stuffs, such  as  canned  meats,  bacon,  etc.,  purchased  from  surplus 
Army  stores,  and  also  a  quantity  of  evaporated  vegetables  and  soup 
powders.  Their  supplies  and  equipment,  weighing  nearly  three  tons, 
is  packed  in  a  large  number  of  boxes  of  the  proper  size  for  trans- 
portation by  mule  or  human  porters. 
The  scientific  work  of  the  expedition  is  well  provided  for  in  the 
form  of  all  kinds  of  scientific  apparatus,  collecting  equipment  and 
containers  with  abundant  supplies  of  formaldehyde  and  other  pre- 
servatives. A  full  supply  of  printed  labels  and  note-books  are 
among  the  details  provided,  so  that  collections  may  be  sent  back 
properly  identified  and  ready  for  study. 
The  active  support  and  co-operation  which  has  come  to  Dr. 
Rusby  from  so  many  quarters  is  a  source  of  much  gratification,  and 
the  many  offers  of  assistance  and  tokens  of  interest  and  esteem  have 
greatly  encouraged  the  members  of  the  party  as  they  start  out  on 
this  most  difficult  undertaking. 
The  officials  of  the  H.  K.  Mulford  Company,  which  house  is 
acting  as  sponsor  and  financial  backer  of  this  enterprise,  have  been 
especially  gratified  at  the  generous  attitude  which  institutions  of 
learning  and  Government  Bureaus  have  taken  toward  this  expedition. 
The  hope  has  been  expressed  in  many  quarters  that  the  success- 
ful outcome  of  this  enterprise  will  convince  scientists  and  the  public 
generally  that  complete  and  hearty  co-operation  betwen  large  indus- 
trial and  scientific  institutions  can  be  obtained  to  their  mutual  benefit 
and  on  a  thoroughly  professional  and  altruistic  basis.
