Annual  Report  of  the  Director.

Arizona,  in  December  and  January.  The  object  of  the  expedition 
was  to  make  casts  of  a  number  of  Hopi  Iudians,  for  the  purpose  of 
reproduction.  Mr.  Dorsey,  in  his  report,  says:  "  Although  we  suf- 
fered greatly  from  the  unusually  cold  weather,  and  from  several  mis- 
haps generally  incident  to  a  wagon  journey  in  Arizona,  the  expedition 
was  very  successful,  and,  as  a  matter  of  fact,  we  secured  two  more 
figures  than  we  had  anticipated.  In  addition  to  the  casts,  I  secured 
a  small  collection,  supplementing  the  one  I  made  in  August  last 
year.  This  consisted  chiefly  of  garments  and  paraphernalia  necessary 
for  the  building  of  the  Hopi  groups.  At  this  time  I  also  passed  four 
days  in  exploration  of  the  ancient  Hopi  ruin  of  Homolobi,  near 
Winslow.  Here  we  secured  over  one  hundred  specimens  of  most 
interesting  ceramics  and  a  number  of  stone  implements  and  fetiches." 
During  the  month  of  April,  Mr.  Dorsey  took  advantage  of  the  unusual 
opportunity  offered  by  the  presence  in  Chicago  of  a  band  of  Esqui- 
maux, brought  here  by  Captain  Miner  W.  Bruce,  to  whom  the  Museum 
is  chiefly  indebted  for  its  extensive  Alaskan  collections.  Captain 
Bruce  kindly  placed  these  people,  at  the  disposition  of  the  Museum, 
and  they  came  to  the  building  day  after  day,  until  in  all  casts  of  nine 
individuals  had  been  completed.  These  were  made  under  extremely 
favorable  conditions,  and  the  results  obtained  promise  to  be  entirely 
satisfactory.  In  the  Department  of  Botany,  Mr.  Millspaugh,  the 
Curator,  has  continued  his  work  upon  the  collection  of  North  Ameri- 
can forest  trees,  making  trips  to  Southern  Illinois,  Mississippi, 
Arkansas,  the  Upper  Peninsula  of  Michigan,  and  Northern  New 
York,  during  which  a  large  amount  of  material  was  secured  and 
much  valuable  data  acquired.  The  most  important  field  work  under- 
taken by  the  Department  of  Geology  during  the  year  was  the  equip- 
ment of  an  expedition  for  the  collection  of  vertebrate  fossils  in  the 
Bad  Lands  of  South  Dakota,  Nebraska,  and  Wyoming.  This  was 
intended,  chiefly,  to  begin  a  collection  for  the  purpose  of  repre- 
senting the  structure  and  characteristics  of  the  ancient  vertebrates 
which  inhabited  this  region  during  Tertiary  times.  Mr.  Farrington, 
in  his  report  of  this  expedition,  says:  "  No  region  in  the  world  is 
richer  in  the  remains  of  ancient  mammals  than  that  mentioned,  and 
the  work  of  collecting  and  preserving  them  before  they  decay 
seems  of  paramount  importance.  Aside  from  the  intrinsic  interest 
which  the  structure  of  these  ancient  animals  possess,  it  seems  hardly 
less  than  a  duty  on  the  part  of  the  Museum  to  secure  and  preserve  as 
far  as  possible  these  remains,  as  often  as  they  are  exposed  by  the  hand 
of  Nature.  The  expedition  sent  by  the  Museum  this  year  devoted  its 
attention  mainly  to  collecting  mammal  remains  of  the  White  River
