"They must have got out when the train stopped," said Daddy Brown.
"Then the thing to do," went on Mr. Parker, "is to find out the names of all the stations and water tanks where stops, were made, and telegraph there."
So after some work the railroad people found out the different regular stops the freight train had made, but at none of these places were there any traces of Bunny or Sue.
"Then a water tank stop is our only hope," Mr. Parker said. "Some of the tanks are in lonely places, and if the children got out there they would be taken in charge by the pumpman or switchman. He would have no way of telegraphing back. We shall have to wait until morning."
You can imagine that Mrs. Brown did not sleep much that night. She did not sleep as well as did Bunny and Sue. But in the morning a telegram, sent by Mr. Black through Mr. Sweeney, was received, telling just where the missing children were.
"They're found!" cried Daddy Brown, as he came upstairs to his wife's room, waving the telegram over his head. "They're all right!"
And a little later he and his wife were on the first train going to the village where Bunny and Sue had been so kindly cared for all night.
"Oh, Momsie!" cried Sue, as she rushed into the dear arms. "Oh, Momsie!"
"Well, Bunny boy, you had quite an adventure!" said his father, as he clasped the little chap close to him.
