��How to Change an Ordinary Chair Into a High Chair for Baby

LL. FARRER, of Welland, Ont., had . three little children of high-chair age in his family, but only one high chair. This set Mr. Farrer thinking and eventu- ally the idea of constructing a contrivance for. temporarily changing a low into a high chair took definite form in his mind. After a number of disappointing attempts he evolved the invention pictured.

The .contrivance consists of a wooden seat which can be attached to the back of an ordinary chair by hooking the heavy wire connected with each folding armrest over the back. By turning the spiral of the hooking arrangement the height of the seat can be adjusted to the require- ments of the child using it. When the seat is not in use it can be folded up so as to take but little space.

��poultry without the aid of a human hand. The barrel shown in the accompanying picture contains water which drips from the spout very slowly into the tilting bucket below. A suitable valve regulates the rate at which the water drips into the bucket. It takes eight hours for the bucket to fill. When full it tilts and dumps the water into a trough. From the trough the water flows to a basin, from which the chickens drink. Attached to the weight suspended from the tilting bucket are bells which jingle as the bucket is overturned and remind the chickens that meal time has come, quite in the best boarding-house style. The feed is likewise supplied at regular intervals automatically, from the large can which sur- mounts the apparatus. It flows through a spout into the hopper, and thence on to a curved delivery plate which scatters it in all directions just as if it were thrown out by hand.

The tilting of the water bucket when it is emptied supplies the motive power for operating the device and once started it requires no attention.

��Feeding and Watering the Chickens Automatically

DON'T scatter chicken feed by hand. It is a waste of time nowadays. Nikilas Lappas, of Salem, Massachu- setts, has patented a machine which does the work and never forgets. At regular intervals his apparatus delivers measured quantities of water and feed for
