MARKING LAST OF SANTA FE
TRAIL THE old Santa Fe Trail, the most - famous pathway of the pioneers in America, will soon be marked from beginning to end with the type of granite tablets illustrated here to show the traveler the route of the scout, the Indian, the soldier and the settler. The course through Missouri and Colorado has already been marked with twenty-five or thirty tablets, erected by the Daughters of the American Revolution, and the present tablets are to mark the course of the trail through New Mexico, the last one to be placed in the Plaza in the city of Santa Fe. The first one of the stones in New Mexico will be placed at Lynn. a few miles below Trinidad just over the border. One will stand at Las Vegas, five in the vicinity of Raton, and the others at intervals till Santa Fe is reached. The one destined for the Santa Fe Plaza is a little more elaborate than the others, and bears on its polished face a little map of the trail, showing its beginning and end and the courses of both branches. The others bear merely the lettered inscription shown in the photograph. The tablets are of dark gray Colorado granite, at once durable and pleasing to the eye.
ORIGINAL ASTOR SCALES THIS illustration shows two pairs of
scales and an old-style letter press which were used by the American Fur Company, of which John Jacob Astor was the head. This company was organized on Mackinac Island in 1815, and continued in business until 1852. The original building in which the furs were stored is still standing and is used as a hotel. These scales are in the possession of the Cable estate, which also owns the building in which the historic relic is housed.

THE FAMOUS PRENTICE
PILLAR A PLEASANT ride of two hours from
Edinburgh will bring the visitor along hawthorn-fringed roadways to an architectural gem, Roslyn Chapel. Not the least pleasing feature of this fairylike structure is the marvelous Prentice Pillar with its tale of revengeful jealousy. The story goes that while the chapel was in process of construction, being founded in 1446, the master workman went to the Continent for new ideas. When he returned he found that his apprentice had constructed this wonderful pillar. Enraged beyond bounds by this act, which he considered unwarranted audacity, he seized his sculptor's mallet and killed his assistant on the spot. Furthermore, when the Bishop of St. Andrews, whose diocese included Roslyn Chapel, was in Rome at the time when the chapel was nearing completion, he obtained from the Pope a dispensation to reconcile Roslyn, that is, to cleanse it from the pollution of some deed of violence committed within its precincts. After the publication of “The Lay of the Last Minstrel" Roslyn Chapel became so popular that a coach was started from Edinburgh and a new inn was built, taking the place of the old inn where Boswell and Dr. Johnson dined.
AERO WON'T TURN TURTLE A RESIDENT of Totowa Borough, O New Jersey, has constructed a "non-capsizable" aeroplane, the inventor claiming that, on account of its design, it is impossible for it to turn turtle while in the air. There is no other like it in the country today. Clifford B. Harmon built one, but never installed the engine. There are fourteen of similar make in process of construction in France.
The machine is equipped with a 50horse-power engine and a nine-foot paragon propeller. This strange-looking bird weighs 620 pounds. The circular construction-shown in the picture—is twenty feet in diameter and has a depth of nine and a half feet. The gasoline tank and radiator are inside the massive circular frame, which is made of naid, a specially prepared linen, made in Ire
