Football Deaths and Injuries in 1915

I bought an old book the other day.  Thought these figures for FOOTBALL DEATHS AND INJURIES were quite shocking as compiled by the Chicago Herald, printed in 

St. Paul Dispatch and St. Paul Pioneer Press: Yearbook and Almanac 1916

Year      Dead     Injured

1902         15           106

1903         14            63

1904         14          276

1905         24          200

1906         14          160

1907         15          166

1908         11          304

1909         30          216

1910         22          499

1911         11          178

1912         13          183

1913         14          175

1914         12            60

1915         16            62

This is college only...don't think it has high school, but maybe...it doesn't say.  All the other scores etc. are for college games, so I assume these figures are for college football.
