Note 1 — Chapter XXXVI · THE PENAL COLONY OF KARA.
Reading edition
This is permitted after the expiration of two, four, six, or eight years (or nearly one-third of the punishment), to those who by good behaviour attain to a certain class. They still live on the spot and must work, and after a second period of this half-liberty, they are sent to a better place as exiles. Whilst in the former class they may be re-imprisoned for bad conduct, but not, I find, after they are set free to colonize (except for fresh crimes), as I have stated in my chapter on the exiles, vol. i., p. 35.
