So they reluctantly fell back to the town, the British following slowly, being weary with their seven-mile march over the hills from Lexington. Coming to a little brown house perched on the hillside, one of the thirsty officers spied a well, with the bucket swinging at the end of the long pole. Running up the bank, he was about to drink, when a girl, who was crouching behind the well, sprang up, and with an energetic gesture, flung the water in his face, crying:—

"That's the way we serve spies!"

Before Ensign De Bernicre—for it was he, acting as guide to the enemy—could clear his eyes and dry his drenched face, Tabby was gone over the hill with a laugh and a defiant gesture toward the red-coats below.

In high feather at this exploit, she darted about the town, watching the British at their work of destruction. They cut down and burnt the liberty pole, broke open sixty barrels of flour, flung five hundred pounds of balls into the mill-pond and wells, and set the court-house on fire. Other parties were ordered to different quarters of the town to ransack houses and destroy all the stores they found. Captain Parsons was sent to take possession of the North Bridge, and De Bernicre led the way, for he had taken notes on his former visit, and was a good guide. As they marched, a little scarlet figure went flying on before them, and vanished at the turn of the road. It was Tabby hastening home to warn her aunt.

"Quick child, whip on this gown and cap and hurry into bed. These prying fellows will surely have pity on a sick girl, and respect this room if no other," said Mrs. Brown, briskly helping Tabby into a short night-gown and round cap, and tucking her well up when she was laid down, for between the plump feather-beds were hidden many muskets, the most precious of their stores. This had been planned beforehand, and Tabby was glad to rest and tell her tale while Aunty Brown put physic bottles and glasses on the table, set some evil-smelling herbs to simmer on the hearth, and, compromising with her conscience, concocted a nice little story to tell the invaders.

Presently they came, and it was well for Tabby that the ensign remained below to guard the doors while the men ransacked the house from garret to cellar; for he might have recognized the saucy girl who had twice maltreated him.

"These are feathers; lift the covers carefully or you'll be half smothered, they fly about so," said Mrs. Brown, as the men came to some casks of cartridges and flints, which she had artfully ripped up several pillows to conceal.

Quite deceived, the men gladly passed on, leaving the very things they most wanted to destroy. Coming to the bed-room, where more treasures of the same valuable sort were hidden in various nooks and corners, the dame held up her finger, saying, with an anxious glance toward Tabby:—

"Step softly, please. You wouldn't harm a poor, sick girl. The doctor thinks it is small-pox, and a fright might kill her. I keep the chamber as fresh as I can with yarbs, so I guess there isn't much danger of catching it."

The men reluctantly looked in, saw a flushed face on the pillow (for Tabby was red with running, and her black eyes wild with excitement), took a sniff at the wormwood and motherwort, and with a hasty glance into a closet or two where sundry clothes concealed hidden doors, hastily retired to report the danger and get away as soon as possible.
