352  CONTRIBUTIONS    TO    ECONOMIC    GEOLOGY,  1904.         [bull.  260, 
On  Norwood  Hill,  24  miles  northwest  of  Hughes,  much  ore  is 
shown  in  bowlder  form  at  the  surface.  A  well  at  Norwood  is  said  to 
have  passed  through  25  feet  of  ore,  probably  loose  fragments,  but  with 
little  intermixed  sand  and  clay. 
Veal's  switch  is  3  miles  northwest  of  Hughes.  Here  a  railroad  cut 
shows  the  following  section : 
Section  at  Veal's  switch,  near  Hughes,  Tex. 
Soil inches—  6  to  12 
Yellow  sand  and  sandstone feet__     3  to  8 
Iron    ore do 1 
Yellow    sand inches...  6 
Iron    ore do 6 
Sand do 4 
Iron    ore do 8 
Sand t'eet__     o  to  5 
Iron   ore inches 1  to  2 
Gray  to  chocolate-colored  clays feet__  8  to  10 
The  clays  at  the  base  of  the  section  probably  represent  the  top  of 
the  Sabine  or  Lignitic  beds.  Nodules  and  masses  of  iron  carbonate 
occur  in  several  of  the  ore  horizons  in  this  cut.  While  the  basal  clays 
are  very  evenly  and  horizontally  bedded,  the  sands  and  ore  are 
irregular. 
On  the  Connor  property,  about  4  miles  southwest  of  Hughes  and  1 
mile  from  Veal's  switch,  huge  bowlders  of  iron  ore  are  exposed. 
Some  of  them  are  8  feet  in  diameter,  the  average  being  about  2  to  4 
feet. 
COMPOSITION  OF  THE  ORES. 
In  the  Second  Annual  Report  of  the  Texas  Geological  Survey  are 
given  the  results  of  a  large  number  of  analyses  of  the  brown  hematites 
of  northeastern  Texas.  These  appear  to  have  been  made  on  good 
average  samples,  and  of  course  give  lower  results  than  the  selected 
samples  usually  quoted. 
The  Texas  ores  compare  well  with  the  average  brown  hematites 
of  the  Appalachian  belt,  both  in  content  of  metallic  iron  and  in 
impurities. 
The  values  for  certain  constituents  given  in  131  of  these  analyses 
have  been  averaged  with  the  results  given  as  No.  1  below.  For  com- 
parison, the  analysis  of  a  sample  of  rock  ore  from  the  Ore  Hill  mine, 
of  Connecticut,  which  is  the  source  of  the  famous  u  Salisbury  iron," 
m  added  as  No.  2,  being  quoted  from  volume  15  of  the  Tenth  Census 
Reports.
