Perseverance is an important trait to be cultivated in first efforts at designing; it takes a certain amount of study to understand any branch of mechanism, no matter what natural capacity may be possessed by a learner. Mechanical operations are not learned intuitively, but are always surrounded by many peculiar conditions which must be learned seriatim, and it is only by an untiring perseverance at one thing that there can be any hope of improving it by new designs.

"Countess Lalage," Prout muttered. "But why?"Perseverance is an important trait to be cultivated in first efforts at designing; it takes a certain amount of study to understand any branch of mechanism, no matter what natural capacity may be possessed by a learner. Mechanical operations are not learned intuitively, but are always surrounded by many peculiar conditions which must be learned seriatim, and it is only by an untiring perseverance at one thing that there can be any hope of improving it by new designs.Was the gun I had seen there one of the notorious forty-two centimetre monsters? I should not like to wager my head in affirming that. It was an inordinately unwieldy and heavy piece of ordnance, but during the first days of the war nothing or very little had yet been said or written about these forty-two's, and I did not pay sufficient attention to the one I saw. Only after the fall of Loncin did all those articles about the forty-two's appear in the papers, and the Germans certainly asserted that they destroyed Loncin by means of such a cannon.
