Cyrus Byington: Missionary and Choctaw Linguist by Louis Coleman (Author).

From the Diary of Cyrus Byington

March 11, 1864 (his birthday):  

The last year I revised the Choctaw Grammer... The last effort I hope is my best and will be of use to learners of Choctaw... I commit these efforts in my old age to the Lord. I have enjoyed these labours very much...

In 1867 he wrote:  

This work can be much improved herafter by other hands. It may be compared to the first survey and making of a road in a new country.
