"Oh, how perfectly dear! Just what I wanted! I wonder how he knew? Oh, I just love it!" and she hugged the beautiful box in her arms.

"Humph!" exclaimed Mr. Nestor, a slowly gathering light of anger showing in his eyes. "It is a nice present, but that is a very poor sort of joke to play, in my estimation."

"Joke! What joke?" asked Mary.

"Putting a present in a box labeled Dynamite, and giving us such a scare," went on her father.

"Oh, Father, I'm sure he didn't mean to do it!" Mary said, earnestly.

"Well, maybe he didn't! He may have thought it a joke, and he may not have! But, at any rate, it was a piece of gross carelessness on his part, and I don't care to consider for a son-in-law a young man as careless as that!"

"Oh, Daddy!" expostulated Mary.

"Now, now! Tut, tut!" exclaimed Mr. Nestor. "It isn't your fault, Mary, but this Tom Swift must be taught a lesson. He was careless, if nothing worse, and, for all he knew, there might have been some stray bits of dynamite in that packing box. It won't do! It won't do! I'll write him a letter, and give him a piece of my mind!"

And in spite of all his wife and his daughter could say, Mr. Nestor did write Tom a scathing letter. He accused him of either perpetrating a joke, or of being careless, or both, and he intimated that the less he saw of Tom at the Nestor home hereafter the better pleased he would be.

"There! I guess that will make him wish he hadn't done it!" exclaimed Mr. Nestor, as he called a messenger and sent the letter to Tom's house.
