2. A good government which really understood its responsibilities would put down with any force requisite that most accursed of all British habits, the sale of intoxicating drinks to those who never knew them before. On the heads of these traffickers rests the blood of thousands of their fellow men. 3. Although a large proportion of children have died while under school instruction, there is no proof that education, if properly conducted, tends to extinguish races. And it _is_ possible that by educating outcast native children, these tribes, with whatever mental constitution endowed, may be spared to contribute their quota to human knowledge and advancement. 4. The school diseases, however, indicate that education should be conducted in a very different manner from what it is in England. Physiology would teach us that it is not safe to take the child of uncivilized parents, and to submit it all at once to the restraints of civilization. What is wanted is a careful study of what can and what cannot be done with safety. Time would seem to be a great element in the education of these children. There should be as little interference as possible with their born habits and customs. And that interference should take place gradually and wisely. The probability is that if children could leave school in health, with sufficient training to enable them to enter the pale of civilization, their children would be the more able to bear the required development of the mental faculties. In any case, physical training, and a large amount of out-door work, are essentially necessary to success. 5. We all know how difficult it is to preserve health among dense populations in our houses at home. We may hence infer how much more difficult it is to draw together numbers of uncivilized or partially civilized people, within the same boundary, or under the same roof, without great risk to health and life. Bring a healthy family from the open country into a narrow crowded London alley, and the little ones will die, the elder ones will be sick for, perhaps, the first time of their lives, and the parents will fall into confirmed ill health, to say the least of it. Our home experience hence teaches us the extreme importance of favourable sanitary conditions, whenever an {18} attempt is made to bring the uncivilized within the pale of civilization. Every society which has been formed has had to sacrifice large proportions of its earlier generations to the new conditions of life arising out of the mere fact of change. Only by the greatest care and by the adoption of every requisite improvement can London itself bear the rapid increase of its population without danger from pestilence.
