The  publications  of  the  United  States  Geological  Survey  are  issued  in  accordance  with  the  statute 
approved  March  3,  1879.  which  declares  that— 
^  The  publications  of  the  Geological  Survey  shall  consist  of  the  annual  report;  of  operations,  geological 
and  economic  maps  illustrating  the  resources  and  classification  of  the  lauds,  and  reports  upon  general 
and  economic  geology  and  paleontology.  The  annual  report  of  operations  of  the  Geological  Survey 
shall  accompany  the  annual  report  of  the  Secretary  of  the  Interior.  All  special  memoirs  and  reports 
of  said  Survey  shall  be  issued  in  uniform  quarto  series  if  deemed  necessary  by  the  Director,  but  other- 
wise in  ordinary  octavos.  Three  thousand  copies  of  each  shall  be  published  for  scientific  exchanges 
and  for  sale  at  the  price  of  publication ;  and  all  literary  and  cartographic  materials  received  in  exchange 
shall  be  the  property  of  the  United  States  and  form  a  part  of  the  library  of  the  organization ;  and  the 
money  resulting  from  the  sale  of  such  publications  shall  be  covered  into  the  Treasury  of  the  United 
States." 
On  July  7,  1882,  the  following  joint  resolution,  referring  to. all  Government  publications,  was  passed 
by  Congress : 
"That  whenever  any  document  or  report  shall  be  ordered  printed  by  Congress,  there  shall  be  printed, 
in  addition  to  the  number  in  each  case  stated,  the  'usual  number'  (1,900)  of  copies  for  binding  and 
distribution  among  those  entitled  to  receive  them." 
Except  in  those  cases  in  which  an  extra  number  of  any  publication  has  been  supplied  to  the  Survey 
by  special  resolution  of  Congress  or  has  been  ordered  by  the  Secretary  of  the  Interior,  this  office  has 
no  copies  for  gratuitous  distribution.
