"Good-bye, dear old friend!" they both exclaimed, while the tears streamed down their cheeks. "Again good-bye! and God be with you!" Craft then quickly broke the seals of the ozone bottles, while Hathaway placed the perforated vessel containing the stronetic acid at Cobb's head. Craft then placed all of the eight bottles of ozone in the case, and, wrapping his coat about his arm to cover the hole and prevent the escape of the ozone gas, scattered the contents on either side of the body, but not touching the door upon which Cobb lay. Taking his arm out, the door was fastened, and their attention was given to watching for the time when they should commence turning the small wheel at the side of the case. Save a slight raising of his finger in token of recognition of their last farewell, Cobb had not moved since the closing of the door. At 2:41 his chest was rising and falling in a regular manner, while a slight tremor of the case denoted his heavy breathing. As their watches showed 2:51, Craft turned the wheel its first notch. From that moment on, not a word was spoken by either of them, nor a sound made, save the sharp click of the wheel as it turned onward toward the 45th division. They watched their friend through the glass cover; the heaving of the chest became less and less, the breathing lower and lower, while a purple hue settled upon his body. At thirty-six minutes past four, the last division of the wheel had been reached. Craft then took a spoonful of plaster, and, inserting his hand carefully inside of the case, pulled out the tube from Cobb's mouth, and poured the half-liquid plaster into the hole in the cast. Taking his hand out, the door was carefully fastened and cemented around its edges; the same thing was done around the edges of the lower door. They then put out the fire in the heater, and set the inside spring of the slab door of the pedestal. Going to the case, Craft laid his hand upon it, and then, kneeling at its side, gave way to his grief, and the tears came thick and fast. "Come, Craft," said Hathaway, whose eyes were also filled to overflowing; "come, old boy; it is all over. We have performed our part, and, perhaps, are accessories to a man's suicide. God be with him! he was a noble man, a true friend, and one we will never cease missing." Craft arose, and they passed out into the cool morning air. The marble door swung back upon its hinges, the inside catch gave a sharp sound as it closed upon the latch, and Junius Cobb was entombed alive. Quickly applying the cement to the edges of this door, as they had done to the glass case inside, the two friends, seeing that it was perfectly set, descended the hill and passed out of sight. CHAPTER VI For nearly five years, Jean and Marie Colchis occupied the old house in Duke's Lane.
