I want to construct.

I want to work day and night when the big deeds are to be done.

That's why I wouldn't care for the Army or Navy; it's too idle a life." "An idle life!" exclaimed Dick and Dave in the same breath.
"Yes," Tom went on dryly.

"Did you ever see an Army or a Navy officer ?" "I've seen several of them," Dick replied, "and have talked with some of them." "Same here," added Darrin.
"Did you see the officers in uniform ?" Reade pressed.
"Yes, of course-----" said Prescott.
"Their uniforms were nice and neat, weren't they ?" Tom asked.
"Of course," Prescott answered.
"Then that was because your Army or Navy officers hadn't been doing any hard work that would ruffle the neatness of their uniforms," finished Tom triumphantly, "and there you are! I can dress up on Sundays or holidays, but on the work days, when I'm a civil engineer, I want to wear clothes that show that I'm not afraid to tackle the rough and hard things of life." "Then you might join Dan in being a day laborer," teased Dick laughingly.
"Oh, no! I want to use my brain along with my muscles, and that's why I'm going to be a civil engineer." "Army a Navy officers may have had an easy time of it once," Dave went on warmly, but times have changed.

Our fighting men, to-day, are obliged to hustle all the time to keep up with the march and progress of science.
