It converted them, in fact, for the time, from a group of careless, merry young fellows, into men with a sense of responsibility. Their time when away from the studio had previously been spent in follies and frivolities. They often drank much more than was good for them, smoked inordinately, were up half the night, and came in the morning to work with heavy heads and nerveless hands. Now they were soldiers, men who matched themselves against the invaders of their country, who risked their lives in her defence, and they bore themselves more erectly, a tone of earnestness replaced a languid indifference and a carelessness as to their work, and in spite of some privations in the way of food their figures seemed to expand. The loss of two nights' sleep a week rendered early hours necessary, and ensured sound sleep during the remaining five. The discipline of the studio had been relaxed. The master felt that at such a time he could not expect the same silent concentration on work that it demanded at other times, but he found to his surprise that while they laughed and joked as they painted, they worked none the worse for this, and that in fact there was a general improvement manifest. Cuthbert heartily enjoyed the change; the prevailing tone was more like that to which he was accustomed at the studios of St. John's Wood than was the somewhat strict discipline that had before prevailed in the studio, and he enjoyed the hard work and excitement outside the walls. The fact that they were running the same risks and sharing in the same work was an added bond of union among the students; and, although, when they met, as they very frequently did in each other's lodgings, there was less uproarious fun than before; there was a healthier atmosphere, and more pleasant and earnest talk. Arnold Dampierre was the only exception to the general rule. When in the field he evinced no want of spirit, and upon the contrary was always ready to volunteer when a few men were required to crawl forward at night to ascertain the precise position of the Prussian outposts or to endeavor to find out the meaning of any stir or movement that might be heard towards their front. At other times his fits of moodiness seemed to increase. He was seldom present at any of the gatherings of his companions, but went off after work at the studio was over, and it was generally late at night before he returned to his rooms.
