“ The feeling against slavery is based on moral grounds. Slavery is now held by most civilised men to be absolutely wrong at all times and under all circumstances. But when we turn to consider the class of criminals and convicts, who have also played an important part in colonisation, the same reasoning does not apply. The objection to a system of transportation is relative to the conditions under which it is carried out. ”
