“I want several chemicals. Can I trust you to keep this a secret?” And Reff Ritter looked around the boat-house to see if any outsiders were in sight. No one seemed to be around.

“Yes,” said both Coulter and Paxton, promptly.

“Well, my plan is simply this: From the druggist I will get certain chemicals to be mixed with water. Then, on the sly, we’ll get hold of Ruddy’s outfit. All we’ll have to do is to apply the chemicals to his sword, scabbard, buttons, and clothing. We can dilute the chemicals so that they will act in two, three or four hours, just as we please. At first the chemicals will not show at all, but after the proper length of time they will turn everything they are on a sickly green. I know the action of the chemicals well, for I have used them in photography.”

“That’s a great idea!” cried Coulter. “Let us try it by all means. And we’ll put some on Andy Snow’s outfit, too!”

“Yes, and on Pepper Ditmore’s things,” broke in Paxton. “What’s the matter with doing up the whole Ruddy crowd while we are at it?”

“We will,” answered Reff Ritter. “We’ll make that inspection drill the worst looking affair that ever took place at Putnam Hall!”

“Yes, and bring seven kinds of trouble to Jack Ruddy and his crowd,” finished Coulter.

“I want every cadet to appear in first-class form,” said the young major. “Captain Putnam is depending upon me to have everything perfect.”
