At the other end of the tent, kneeling over a brazier filled with coals, is the third member of the Sanitary Corps. She holds above the coals a retort, in which she is distilling Lily Balm. Her back is toward us and her face is hidden. There! you have caught a glimpse of it as she turned her head to speak to her companion. The cheeks are flushed, the eyes are bright with the glow of the coals, there is an earnest, pitiful look in their deep blue that speaks of thought intent upon present duty. But there is also a strange light therein, a light as from some far away world, that throws an air of mystery around this person and bids your thoughts pause reverently as they run on in judgment concerning her. This is Faith, the daughter of Rodney the Commodore. She is young as the Brownies count years, and was born "at sea," that is, upon the Lake Katrine of Brownieland, through which flows the Rivulet at the foot of the Orchard. [Illustration: FIG. 38.--A Peep Inside the Sanitary Tent. Faith Distilling Lily-Balm.] At Faith's side is her companion and friend, Sophia, the daughter of Pipe, the Boatswain. There is a mixture of boldness and shyness in her manner that strikes one at once. Her movements have the snap and positiveness of a practical woman. Her eyes sparkle with intelligence; there is in them a keen, questioning look which tells that she loves not only to know, but to know the reason why. If she were not a Brownie you would probably say she was a pushing sort of person; that you scarcely could decide whether she was more curious or sincere, more dreamy or practical, more skeptical or credulous. But that she is beautiful you would not hesitate to say. She is busy among the herbs, sorting them, making ready material for Faith's retort. Now that you have seen this Sanitary Corps, and learned their names, you may drop the door of the tent and we shall go on with the story. "Come, Grace, we have done quite enough for the present," said Agatha. "Bring the bandages and let us go to the Hospital. Have you lint and balm in your satchel? Very well. That is all we need now. Faith, hadn't you better leave off distilling, and help us for a while with the dressing?" "Yes; if you wish it," answered Faith, "and we can stop now as well as not."
