I forget what it was , bombing probably , or the use of trench mortars , possibly map reading or -- a subject part of the school curriculum of our grandmothers -- the use of globes . The army has a passion for imparting knowledge of any kind to temporary lieutenants . I went to sleep while Thompson was explaining just where the boy 's particular course of instruction was given , a camp some three or four miles out of X. Thompson has an amazing knowledge of what naturalists would call the habitat of the various parts of the army . At 3 a.m. I was awakened from my sleep . We had reached , an hour late , the junction at which we had to change . Thompson and the boy were both alert and cheerful . They had , I fancy , been talking all the time .
