"Oh, none of us will dare show ourselves outside the grounds," returned Ruth, blushing. "Miss Garwood wouldn't permit it."

"Well, if we get the chance, we may come up as far as yonder side fence," put in Fred. "If we do, we'll give you the signal—three long whistles."

Nearly all of the cadets at Colby Hall were ready for Hallowe'en fun. They dressed up in all sorts of disguises, including those of monks, Indians, negroes, and ghosts. Lighted pumpkins with grinning faces cut into them were likewise numerous; and one senior trailed around in a silk gown which he had brought from home for this very occasion.

When the Rover boys appeared dressed as young ladies, with girls' hats on their heads and parasols in their hands, they were greeted with a loud cheer, and this was redoubled as they marched around the campus arm in arm with several boys dressed as dudes, and one attired as an admiral.

"Some class to the Rovers, and no mistake!" was Spouter's comment. He had on a pair of long whiskers, a linen duster, farm boots, and a big straw hat.

"How do you do, Uncle Si?" cried Andy, coming up to him and bowing. "How is corn?"

"So high, by gosh! y'u can't see the house," answered Spouter in country dialect. "Do tell, leetle gal! but y'u do look mighty purty, y'u do!" and at this there was a general snicker.

At the first opportunity, the Rovers and several of their friends slipped away from the campus and hurried off in the direction of Clearwater Hall. They were lucky enough to meet a big wagon, the driver of which was going to the next town to pick up some young folks for a straw ride. This man took them to the young ladies' school just for the sport of it.

When the Rovers gave the signal, Ruth and her friends came running towards the side fence of the grounds. All were attired in male costumes, wearing exaggerated collars, cuffs and neckties. In addition, Ruth had on a big pair of pick-toed shoes and a silk hat many years out of date. She also carried a silver-headed cane.

"Oh, don't you want to take us out for a walk?" questioned Andy, in a high-pitched, feminine voice.
