Unless we are very lucky we shall sometimes lose ourselves in a sudden and dense fog of ignorance.
Wherever we go we must carry our warm cloak of human sympathy and understanding for vast tracts of land will prove to be a sterile desert--swept by icy storms of popular prejudice and personal greed and unless we come well prepared we shall forsake our faith in humanity and that, dear boys, would be the worst thing that could happen to any of us.
