Whenthe track apparatus is operated from,. tower a repeater instrument is pro-vided which shows the state of thetrippers and if they are moved by apassing train or maliciously or acciden-tally disturbed, a bell rings in thetower and continues ringing until stop-ped. This provides for any failure ofthe trippers. The apparatus shown hasbeen designed for the vacuum brake, as. FIG. 4.

In a recent visit to one of the greatlocomotive construction works it was ob-served that mechanical appliances hadreached such an infinite variety of usesthat machinery seemed to be doing every-thing except perhaps chipping a air hammer is now getting its workin on this also. The chipping of a sad-dle, like the shoeing of a horse, is likelyto remain a portion of the worlds workwhere handicraft cannot be supersededby mechanical devices. Chipping a sad-
