ler and stouter and developed his muscles.
Tom and Harry employed him at the mine as a checking clerk, where
he actually earned his money, and saved a goodly amount of it
every month.

"Tom, you rascal, you promised some day to show me how you scared
that boy stiff with your rattlesnake click," Harry reminded his
partner.

"Nothing very difficult about it," laughed Tom. "Can you make
a noise by grinding your molars together---your grinding teeth?

"Keep on practicing, and you'll get that rattle down to
perfection---that's all," nodded Tom.

Spring found the young engineers restless for new fields. They
longed to tackle other big feats of engineering. Jim Ferrers
understood, and said to them:

"You youngsters know, now, that you can trust me to run this mine."

"We always knew that we could trust you," Tom corrected him.

Tom and Harry delayed but a couple of hours at Dugout. Then-----

However, their further adventures must be delayed in the narration
until they appear between the covers of the next volume in this
series. It will be published at once under the title, "_The Young
Engineers In Mexico; Or, Fighting the Mine Swindlers_."

In this new volume will be described what Tom and Harry did in
a land of mystery and romance; a land where the sharp contrasts
of wealth and squalor have fostered the development of many noble
characters and have created some of the vilest among men. The
forthcoming story is one filled with t
