The first volume of this series is called “The Moving Picture Boys,” and in that I introduced to you Blake and Joe.

They worked on adjoining farms, and one day they saw a company of moving picture actors and actresses come to a stream, near where they were, to take a “movie drama.”

Naturally Blake and Joe were interested at once, and making the acquaintance of Mr. Calvert Hadley, who was in charge of the taking of the play, or “filming it,” as the technical term has it, the two boys were given an opportunity to get into the business.

They went to New York, and began the study of how moving pictures are taken, developed from the films, the positives printed and then, through the projecting machine, thrown on the screen more than life size.

The process is an intricate one, and rather complicated, involving much explanation.  As I have already gone into it in detail in my first book of this series, I will not repeat it here.  Those of you who wish to know more about the “movies” than you can gain by looking at the interesting pictures in some theater, are respectfully referred to the initial volume.

Joe and Blake were much interested in the Film Theatrical Company.  My former readers will well remember some members of that organization—­C.C.  Piper, or “Gloomy,” as he was called when not referred to as just “C.C.”; Birdie Lee, a pretty, vivacious girl; Mabel Pierce, a new member of the company; Henry Robertson, who played juvenile “leads”; Miss Shay, and others in whom you are more or less interested.

After various adventures in New York City, taking films of all sorts of perilous scenes, Joe and Blake went out West, their adventures there being told in the volume of that name.  They had their fill of cowboys and Indians, and, incidentally, were in no little danger.

Afterward they went to the Pacific Coast, thence to the jungle, where many stirring wild animal scenes were obtained, and afterward they had many adventures in Earthquake Land.  There they were in great danger from tremors of the earth, and from volcanoes, but good luck, no less than good management, brought them home with whole skins, and with their cases filled with rare films.

Having finished in the land of uncertainty, the work assigned to them by Mr. Hadley and his associates, Joe and Blake had gone for their vacation to the farm of Mr. Hiram Baker, near Central Falls.  But their intention of enjoying a quiet stay was rudely interrupted.

For not long after they had arrived, and were resting quietly under a cherry tree in the shade, Mr. Ringold, with whom they were also associated in moving picture work, called them up on the long distance telephone to offer them a most curious assignment.

This was to go to the flooded Mississippi Valley, and get moving pictures of the “Father of Waters” on one of “his” annual rampages.

Of course Blake and Joe went, and their adventures in the flood fill the volume immediately preceding this one.
