"Bring down a load of artesian wells!" jeered Ned.

"An artesian well, my boy, is nothing more than a hole in the ground," the guide informed him, much to Chunky's chagrin.

The spot where the divining rod had so suddenly gotten busy was about midway of an old water course, covered with a thick growth of bunch grass.

"Get some tools, boys," directed the Professor.

Tad ran back to camp, which lay some distance to the east of where they were gathered. Searching out a pick and two shovels, he leaped on his pony, dashing back to the arroyo.

"That was quickly done," smiled Santa Claus. "Are all of you lads as quick on an errand as that?"

"Only Chunky," answered Ned solemnly.

The guide began to dig, in which effort he was joined by Stacy Brown, who, with a shovel, caved in about as much dirt as he threw out.

"Here, give me that shovel," commanded Ned. "You'll fill up the bole before we get it dug."

Tad, having tethered his pony, took the extra shovel and went to work.
