(      Nov.,  1881. 
it  is  distant  about  12  miles,  and  the  peaks  of  which  can  be  traced  for  a  dis- 
tance of  nearly  200  miles.  The  broad  streets  are  shaded  by  cottonwood 
trees  and  are  mostly  bordered  by  rivulets  of  water  brought  twenty  miles 
from  the  mountains  for  irrigation.  The  buildings  are  attractive  and  even 
elegant,  and  the  streets  and  stores  are  in  many  instances  illuminated  by 
the  electric  light.  At  the  Windsor  Hotel  the  comforts  of  a  first-class, 
house  were  found. 
On  the  following  morning  the  party  was  joined  by  six  members  who  had 
left  Kansas  City  on  Friday  evening.  Various  places  of  interest  were  vis- 
ited, and  in  the  afternoon  a  visit  was  paid  to  the  works  of  the  Boston  and 
Colorado  Smelting  Company  at  Argo,  permission  having  been  obtained 
through  the  courtesy  of  Senator  Hill.  In  roasting  the  ore  the  sulphides 
are  converted  into  sulphates,  the  silver  sulphate  is  dissolved  in  water,  the 
metal  is  precipitated  hy  copper  plates  and  the  dissolved  copper  is  recovered 
by  precipitation  with  iron  plates. 
From  Denver  to  Colorado  Spring  and  Manitou,  the  railway  ascends  the 
valleys  of  the  Platte  and  of  Plum  creek,  until  Divide  is  reached,  having 
an  altitude  of  over  7,000  feet,  or  2,000  feet  higher  than  Denver.  Palmer's 
Lake,  situated  on  the  summit,  has  an  outlet  northward  to  the  Platte  and 
southward  to  the  Arkansas  river.  Tlie  curious  forms  of  the  rocks  along 
Plum  creek — suggestive  of  castles,  towers  and  fortifications — give  place  on 
the  southward  trip  to  the  weird  and  fantastic  monument-like  structures  of 
Monument  Park,  a  corner  of  which  is  traversed  by  the  railway.  From 
Manitou,  where  several  other  members  were  met,  who  had  come  by  way 
of  Pueblo,  excursions  were  undertaken  to  the  Garden  of  the  Gods,  with 
its  balanced  rocks  and  grotesque  masses  of  red  sandstone  and  white  stone, 
toAvering  often  perpendicularly  to  the  height  of  300  or  400  feet ;  to  Ute  Pass 
and  Rainbow  Falls ;  to  Williams'  Cafloii  and  the  Cave  of  the  Winds  ;  to 
the  various  mineral  springs  and  to  the  numerous  tents  where  many  resi- 
dents of  Western  cities  rusticate  during  the  summer  months. 
On  Tuesday  morning  several  of  the  party  ascended  Pike's  Peak,  14,147 
feet  high,  but  only  8,000  feet  above  Manitou.  The  larger  number  took  a 
drive  to  South  Cheyenne  Canon,  with  its  imposing  i3recipitous  walls,  and 
at  the  head  of  which  a  lively  stream  of  water  falls  in  seven  cascades  from 
the  height  of  nearly  500  feet.  The  entire  party  reached  the  Windsor,  at 
Denver,  on  the  same  evening. 
On  Wednesday,  August  31st,  a  westward  trip  was  taken  by  a  narrow- 
gauge  branch  of  the  Union  Pacific  Railroad.  At  Golden,  15  miles  from 
Denver,  the  road  enters  Clear  Creek  Caiion,  having  been  cut  into  the  solid 
rock,  the  cliffs  towering  on  either  side  almost  vertically  to  the  height  of 
from  1,000  to  2,500  feet.  From  the  town  of  Black  Hawk,  the  railroad 
climbs,  by  a  series  of  "switchbacks  "  five  miles  in  length,  the  mountain 
sides,  until  it  reaches  Central  City,  distant  one  mile  but  located  500  feet 
higher,  at  an  altitude  of  8,343  feet.  Here  the  tunnel  in  course  of  construc- 
tion by  the  Bonanza  and  Union  Mining  Tunneling  Company  was  visited, 
also  the  entrance  of  the  Bobtail  Mine  and  the  stamping  mill  of  the  latter, 
where  the  precious  metals  are  extracted  from  the  ore  by  the  amalgamation 
process.
