The second class of convicts is subdivided into five classes, namely, 1. Exiles sentenced to labor in the manufactories; 2. Those sentenced to form part of the labor companies engaged on the public works; 3. Those allowed to work at their respective trades; 4. Those hired out as domestic servants; and 5. Those destined to become colonists. The last-mentioned of these are at once established on the waste lands allotted to them, each person obtaining an area of not less than thirty acres, and being besides furnished with materials for building a house, with a cow, some sheep, agricultural implements, and seed corn. During the first three years these settlers are exempted from all imposts; during the next seven years they pay half the usual amount of taxes, and in addition to this, fifteen silver copeks annually toward an economical fund erected for their benefit. After the lapse of these ten years they take their rank among the other crown peasants, and are subjected to the same burdens. Except when especially pardoned, these colonists are not either allowed to change their condition, or arbitrarily to quit the lands allotted to them. Colonization, according to this system, being found excessively expensive, and at the same time very precarious, on account of the frequent desertion of the colonists, who, living without families, were bound by no ties, was given up in 1822, but has since been resumed. In order to promote the speedy amalgamation of the convict population with the free population, the government bestows on every free woman who marries one of these colonists a donation of fifty silver rubles; while the free man who takes to wife a female convict receives a donation of fifteen rubles. Persons enjoying the privilege of collecting gold from the sands of the government of Tomsk, and who employ convicts for the washings, are bound to pay, in addition to the daily wages, one ruble and fifteen copeks in silver toward the economical fund. The convicts employed as domestic servants are fed by their employers, and receive in wages one silver ruble and a half per month. After eight years of such compulsory service, these exiles may also become colonists, and be enrolled among the peasants of the crown. Convict colonists may, should the authorities deem it expedient, be allowed to work at trades in the towns, but they must not become members of corporations or guilds, and must never be considered as being withdrawn from their condition of colonists.
