Private Quelch looked like a 'Professor' when the author first met him at the training depot. Why?
When the narrator first saw Private Quelch at the training depot, Quelch appeared lanky, stooping, frowning through horn-rimmed spectacles and the narrator understood why the person was known as The Professor. The narrator also said that if anybody had any doubts on the subject, a five minutes conversation with The Professor would clear them all.
Private Quelch laid his first impression in the first musketry class in which he went on correcting the Sergeant on the muzzle velocity or speed at which a bullet leaves a rifle, and how on being questioned by the Sergeant, The Professor boasted about his “intelligent reading”. It was a phrase that became familiar to the platoon. That was introduction of Quelch to all.
