Tapping Other Species. — According to unpublished notes loaned the 

 writer by Cuif in 1912, he has concluded finally that the tapping of 

 Austrian or Scotch pine will never be commercially practicable ■without a 

 decided increase in present turpentine and rosin prices.-'' This agrees 

 with the results in other forests which are not usually tapped for resin. 

 For example, in Corsica, during the extremely high prices caused by the 

 American Civil War, Corsican pine had been tapped for awhile and then 

 abandoned ; the same was true of California yellow pine.
