She flew along the veranda to a window and pressed it upward. It yielded, and her joy flowed like a river. Up she flung it, far up, and with a bound the active form was upon the sill and disappeared into the room. The letter lay where she had left it, and in a moment the precious passport was in its hiding-place. A moment later, the gate swung shut behind her. Her bosom throbbed with a new courage as it felt the touch of the letter that was entrusted to its keeping; for this was her warrant, her pledge of passage on that long journey towards which she pressed so eagerly. Oh, woman! who countest pestilence thy friend when it is in league with love!
On she pressed, on through the frosty night. The snow made music beneath her hurrying feet, the bridge by which she crossed the river cracked and echoed with the frost, and the Northern lights flashed the signals of their heavenly masonry—for what knew they of plague and love and sorrow, and of the story of this poor tracing-board of time?
But Margaret never thought of this, for she, too, had her own secret symbols, and her heart its own mighty language, voiced, like the other's, in alternate floods of light and gloom.
She never paused till she was challenged by the guard before the plague-struck house. Then she laid down her travelling-bag, for it had grown heavy; but her eyes never turned from the dim light that shone from the window. Love and danger were there, and the fascination of both was upon her.
"Where might you be goin', miss?" said the guard. His voice was thick, and his breath bore a perfume which proved he had been hospitably entreated by some sympathetic friend. Doubtless it was the good Samaritan's wine that had failed of its destination.
"I am going into that house, if you please," replied Margaret. "I am going to take care of Mr. Strachan. The health officer has asked for a nurse."
"Oh, no, my lady," said the guard, "no pretty face like yours is going to be marked by the smallpox." His chivalry was of the moist kind, and his emotion made him hiccough several times.
Margaret winced: "I am entitled to go in," she said boldly, "and I will thank you to let me pass," with which she picked up her valise.
"Not by no means," the guard rejoined. "I've got orders not to let no one in without a letter from the officer."
"I have the letter," said Margaret, for in her excitement she had forgotten it. She produced it and handed it to the man. He walked over to a gas lamp across the street. Feeling the need of exercise, he proceeded thereto by several different routes. Having reached it, he was seized with a great fear lest the iron post should fall, and lent himself to its support. Then he read the letter over aloud; three or four times he read it, punctuating it throughout with the aforesaid tokens of emotion. He returned to where she stood, selecting several new paths with fine originality.
