When the cement has set and the wall is being tilted upright the dry sand simply runs out, leaving the dead air space which is not a conductor of heat or cold. So much for the utility of the system. From the aesthetic standpoint quite as much has been accomplished, as it has been demonstrated that an inexpensive factory building can be made as handsome as an art museum or an exposition hall. The most elaborate ornaments can be applied in an economical manner. The method of preparing the cement ornaments is very ingenious. First a model is made in clay from the artist's sketch. We will suppose it to be a decorative frieze to extend the length of the building. From this clay model a plaster paris cast is taken and from the latter is made a gelatine mould, which hardens to a rubber-like consistency. When this is stripped off, cement can be poured into the gelatine which retains every detail of the original clay model. As soon as the cement is hard enough the gelatine can be taken off and used again and again until all the sections of the frieze have been completed. If the gelatine mould shows wear after a number of pourings, a new one can be easily prepared. All these ornamental details are reinforced with projecting rods, and when the façade of the building is to be poured, the frieze, capitals, etc., are placed on the form before the pouring; the reinforcements holding them in place.

It is claimed that old pipe which has been dug up can be coated with cement by this method and used again, unless, of course, it has deteriorated to a great extent. The two pictures here shown were taken in southern California, where pipes are being prepared for use near San Diego. The use of concrete in this connection, is another triumph of this material over the ordinary materials that have hitherto held full sway in this sort of construction work. It would seem to sound the doom of the old. ONE-ARMED ORCHESTRA THERE is an orchestra in Portland, Oregon, which is composed exclusively of one-armed men. In spite of their physical shortcoming, these determined, enthusiastic young men are making a practical success out of their association. The idea of this orchestra originated with B. R. Amend, a musician. The loss of his arm did not induce him to despair of somehow making an honorable competence. He set his wits at work and conceived the idea that he could not be the only musician in the world with one arm. He began to scour the city of Portland and the State of Oregon. Ere AN ORCHESTRA MADE UP EXCLUSIVELY OF ONEARMED MEN. long, he was in communication with not only one but several who had lost arms and were of musical temperament or training. Eight members compose the orchestra, seven with their right arms gone, but the eighth, Mr. Lester Cox, is minus the left. It is a peculiar fact that every member lost his arm through service in the mills of Oregon and Washington! The orchestra, sensibly, does not go in for classical music, but strives its best to render popular and dance music-the kind the people most appreciate and for which there is ten times the demand. Mr. Amend, handicapped as he is, furnishes a show in himself, as he dexterously and with at times, marvelous skill manages to keep the piano going in time. and tune with the instruments about him. It is hard enough to accompany an orchestra when the pianist has two hands and clever musical ability. What must it be when a chap has but one hand with which to manipulate the bass and high keys? Probably the most difficult and sensational feature of the concerts and entertainments is the stunt performed by Messrs. Amend and Tienken. They give a guitar solo, both playing on one instrument.

MILK DELIVERED BY WIRE HE owner of a small dairy out west THE got tired carrying the heavy cans of milk from his milking sheds to the creamery, and as the latter building was only about three hundred feet distant and on a lower level he devised the aerial milk carrier shown in the photograph. The full cans are carried above a county road, but as that is on a lower grade than the land on both sides it does not interfere with traffic. The little trolley, carrying a twenty gallon can, is run to the creamery by gravity while the empty cans are hauled back very easily by rope. Stanley L.
