The matter was quickly arranged, and Shadow Hamilton was also included in the party. The ice-boat was rather crowded, but that only added to the sport.
"Hold tight, everybody!" cried Henshaw, as he raised the sail. There was a good, stiff breeze, and in a minute the _Snowbird_ was bowling along in grand style, the students shrieking their delight as they passed their numerous friends on skates.
"Come along and race!" cried Roger, to Sam Day.
"Give me a tow and I will," was the merry reply.
"Be sure to return when you get back!" called out Ben Basswood, and this remark caused a general laugh.
"Do you remember the ice-boat race we had with the Rockville cadets?" said Messmer.
"Yes, and the accident," replied Dave. "We don't want to run into anything again."
"I say, fellows, let us visit that cabin on the island!" cried Roger. "Maybe we'll find out something more about Pud Frodel and that other fellow."
The senator's son referred to a cabin located on a lonely island some distance from Oak Hall. Here it was that the lads had discovered the two robbers with whom Nick Jasniff had been associated, and had given to the authorities the information which had led to the rascals' capture.
"I'm willing to go," said Henshaw. "Only we can't stay on the island too long, for we'll have to get back before it gets too dark."
As the ice-boat swept along they passed quite a number of boys on skates. Presently they came to a crowd of six, all attired in neat semi-military uniforms.
"Hello, Oak Hall!" was the cry.
"Hello, Rockville!"
"Where are you going with that tub?"
"Looking for another Rockville boat to beat!" sang out Henshaw. How he had once won an ice-boat race against the military academy lads is already known to my old readers.
"Go along, we're going to build a boat that will leave you away behind," retorted one of the Rockville cadets.
"Brag is a good hoss, but Get-there takes the oats!" cried Dave, and then the _Snowbird_ swept out of hearing of the military academy lads.
"They didn't like it at all, that we beat them," was Roger's comment. "Wonder if they will try to build a swifter boat?"
"Let them come on," answered Dave. "We can build another boat, too, if it's necessary."
"Say, their blowing puts me in mind of a story," came from Shadow Hamilton. "Two little boys----"
"Oh, Shadow, another?" groaned Messmer, reproachfully.
"Let him tell it, it will help to pass the time," remarked Henshaw. "I know it's all about two poor lads who were caught in a snowstorm and had to shovel their way out with nothing but toothpicks."
"No, it's about two boys who sold suspension bridges for a living," cried Dave, merrily. "They sold as high as eighteen a day, and----"
"Say, if you want to hear this story, say so," demanded Shadow. "These little boys got to bragging what each could do. Says one, 'I kin climb our apple tree clear to the top.' Says the other, 'Huh! I can climb to the roof of our house.' 'Hum,' says the first boy, 'I can climb to the roof of our house, an' it's higher'n yours.' 'No, 'taint.' 'It is so--it's got a cupola on top.' 'I don't care,' cried the other boy. 'Our's is higher. It's got a mortgage on it--I heard dad say so!'" And a smile went the rounds.
Not having any other name, the boys had christened the place for which they were bound, Robber Island. It was a lonely spot, rocky in some places and covered with woods and underbrush in others. The shore was fringed with bushes, through which the driven snow had sifted to a depth of two feet and more.
"Here we are!" cried Dave, as they came in sight of one end of the island. "Lower the sail, or we'll be sliding into the trees and rocks."
They made a safe landing, and then prepared to walk to the cabin, which was some distance away. Henshaw looked doubtfully at the ice-boat.
"Think she'll be all right?" he asked, of Messmer.
"I think so."
"Oh, sure she'll be all right, with the sail down," added Roger.
"Wonder if there are any wild animals on this island?" questioned Shadow.
"Might be an elephant or two," answered Dave, "or half a dozen royal Bengal tigers."
"Quit your fooling, Dave. I reckon you wouldn't want to meet a bear or a wildcat any more than myself."
"No bears around here," said the senator's son. "Might be a wildcat though, or a fox. I'm going to get a good stick."
Each student provided himself with a stout stick, and then the whole crowd moved forward in the direction of the cabin in the center of the island, never dreaming of the astonishing adventure in store for them.
CHAPTER X
AN ADVENTURE ON ROBBER ISLAND
The way to the lonely cabin was not an easy one. There was no path, and they had to scramble over rough rocks and across fallen trees and through thick masses of brushwood. They forgot about the gully, and only remembered it when they found themselves floundering in snow up to their waists.
"For gracious' sake!" cried the senator's son, as he crawled out the best way he could. "I fancied the bottom had dropped out of everything!"
"I remember this hollow now," answered Dave. "We haven't got much further to go."
It was a clear December day and quite light under the leafless trees. There were a few evergreens scattered about, but not many, and these hung low with their weight of snow. All was intensely silent.
"This ought to be lonely enough to suit anybody," observed Henshaw. He turned to Roger. "How would you like to come out here some dark night all alone?"
"None of that for me," was the quick answer.
"Might meet a ghost," said Dave, with a smile.
"Talking of ghosts puts me in mind of a story," said Shadow. "A boy once had to go through a dark woods all alone----"
"Shadow wants to get us scared," interrupted Dave. "Oh, Shadow, I didn't think it of you! It's bad enough as it is," he went on, in seeming reproach. "Don't you know this island is haunted by the man who committed suicide here?"
"A suicide, Dave?" cried the school story-teller, forgetting all about the tale he had been on the point of relating.
"Sure. That man tried to kill his wife and seven children, and then hung himself from a tree not far from here. They say that twice a month his ghost appears."
"It's about time for the ghost now," added Roger, scenting fun. "Listen! Didn't I hear a groan!"
"Must have been that," went on Dave. "There it is again!"
"I--I didn't hear anything," faltered Shadow. He was not an excessively brave lad at the best.
"It's getting pretty dark," continued Dave. "That is when the ghost shows itself, so I've been informed. If we---- Look! look!" he yelled, pointing over Shadow's left shoulder.
The story-teller gave a leap forward and glanced around hastily. Dave was pointing to a clump of bushes.
"Wha--what did you see?" asked Shadow, in a shaking voice.
"I don't know. It was tall and white----"
"The
