Nothing daunted by their trying experiences the Pony Rider Boys set out on the concluding trip of the season—a journey over the historic plains and mountains of New Mexico. After a long railroad ride, they had finally arrived at the town of Bluewater, from which they were to begin their explorations in the southwest.

A guide was to meet and conduct them across the mountains of the Zuni range and so on to the southern borders of the state.

By the time they reached the platform of the station, the stock car had been uncoupled and was being shifted to a side track where they might unload their belongings at their leisure.

"I wonder where that guide is," said Tad.

"He was told to be here," answered the Professor.

"Never mind; we can unload better without him," averred Ned, starting off at a brisk trot for their car which had been shunted alongside the platform at the rear of the station.

With joyous anticipation of the new scenes and experiences that lay before them, the lads set briskly to work, and within an hour had all the stock and equipment removed from the car.

There was quite an imposing collection, with their ponies, their burros, tents and other equipment, the latter lying strewn all over the open level space beyond the station.

"Looks as if a circus had just come to town," laughed Walter.

"We've got a side show, anyway," retorted Ned.
