"There is another reason why I fancy your boy, and think I can make an engineer of him," continued Mr. Hobart. "His physical condition seems to me to be perfect. As they say of prize animals, he seems to be sound in wind and limb, and without a blemish. Now, the life of an engineer, particularly in unsettled countries, is a hard one. He is exposed to all sorts of weather; must often sleep without a shelter of any kind, and must work hard from early dawn until late at night, sometimes on a scanty allowance of food. It is as hard as, and in many cases harder than, active service in the army. It is no life for weaklings, and we do not want them; but, from what I have seen of your boy, I do not believe that even you can point out any physical defect in his make-up."
