"Hippy darlin'!" cried Nora. "If Hindenburg jumps out he will hang himself and choke to death."

"Sure he will. That is why he isn't going to jump out."

Hindenburg stood up in the bag and barked in apparent approval of Hippy's assertion.

"Listen!" exclaimed Emma, holding up a hand. "Bark again, Hindenburg."

Hindenburg did so, Emma Dean giving close attention.

"What is the big idea?" demanded Lieutenant Wingate.

"I wished to listen to this voice from the canine world because it carries a message to us," answered Miss Dean gravely.

Hippy gave her a quick keen glance, but Ginger, taking sudden umbrage at a dog barking at his side, demanded his rider's exclusive attention. By the time Hippy had subdued the bronco, Emma's peculiar remark had passed out of mind. Soon after that, with packs neatly lashed, each rider in the saddle, the Overland Riders wheeled their ponies and jogged along the village street on their way to the Great North Woods where Tom Gray, as an expert forester, was to "cruise" or estimate the amount of timber standing on the thousands of acres in the huge timber tract, the largest tract of virgin timber east of the Rocky Mountains.

The Overland Riders, who, for the previous three summers, following their return from France where they had served in various capacities during the war, in the Overton College Unit, had decided to accompany Tom to the Big Woods, seeking such adventure as the northland might afford.

As they started away on the first leg of their journey, none was more joyous than the bull pup, who barked at the villagers, barked at every dog and cat within sight, and, after the village had been left behind, entertained himself by barking at imaginary cats and dogs, Emma Dean being his most interested listener. Emma's quietness attracted the attention of her companions, and they wondered at the change in her, for, on previous journeys, there was seldom a time when Emma did not have a great deal to say.
