Masks had not yet been invented, and in consequence play was necessarily stiff and slow, as the danger of the loss of sight, or even of death, from a chance thrust was very great.

When Rupert first began his lessons, he was so rash and hasty that his grandfather greatly feared an accident, and it struck him that by having visors affixed to a couple of light steel caps, not only would all possibility of an accident be obviated upon the part of either himself or his pupil, but the latter would attain a freedom and confidence of style which could otherwise be only gained from a long practice in actual war.

The result had more than equalled his expectations; and Monsieur Dessin had, when he assumed the post of instructor, been delighted with the invention, and astonished at the freedom and boldness of the lad's play.

It was, then, thanks to these masks, as well as to his teachers' skill and his own aptitude, that Rupert had obtained a certainty, a rapidity, and a freedom of style absolutely impossible in the case of a person, whatever his age, who had been accustomed to fence with the face unguarded, and with the caution and stiffness necessary to prevent the occurrence of terrible accident.
For another half hour the lesson went on.

Then, just as the final salute was given, the door opened at the end of the room, and a lady entered, in the stiff dress with large hoops then in fashion.
Colonel Holliday advanced with a courtly air, and offered her his hand.
