The protector consists of a mask, flexible tubing, 

 intake funnel and head straps. It supplies fresh 

 air without any pressure furnished by machinery 



Breathing Fresh Air in a Manhole 

 through a Protector Mask 



before peeling. Each piece should 

 weigh not less than one and one-half 

 ounce. These pieces are planted in 

 shallow window boxes in leaf mold, 

 coconut fiber or sand. The boxes 

 are kept in the window of a cool but 

 frost-proof room and the sprouts are 

 grown in them until they are from 

 one-half to one inch high. Then 

 they are planted as seed potatoes. 



To prevent the cut pieces from 

 shriveling before they are planted, 

 the cut surface is dusted over wdth 

 dry, powdery plaster of Paris, dry 

 slaked lime, or finely powdered char- 

 coal. The rose end of the potatoes 

 is hardly missed, and the seed 

 potatoes are thus obtained at a 

 scarcely appreciable cost. 



A WESTERN manufacturer has put a 

 gas protector on the market which is 

 designed to enable a man to breathe pure 

 air without pressure while he is working in a 

 manhole repairing gas pipes or wire 

 conduits. It has several distinctly novel 

 features. The pure air is drawn through 

 the intake funnel and tubing fastened over 

 the mouth and nostrils, and the used air is 

 expelled through an exhaling valve. 



The protector weighs but seven 

 ounces. The mask is constructed of 

 rubber and aluminum. Adjustable 

 head straps hold it firmly in place and 

 make an air-tight fit, as the rim of 

 the rubber mask is inflated through 

 an air valve blown up by the 

 mouth each time a breath is taken. 

 The flexible tubing is twelve feet 

 long and is equipped with an 

 intake funnel at its end. 



Portable Saw and Pump Outfits for 

 Farm Use 



OF great utility about the farm is the 

 small motor and stand shown in the 

 accompanying illustration. It can be 

 carried about in a wheelbarrow and may be 

 used to saw wood, operate a pump, washing 

 machine, churn or even to charge a storage- 

 battery. Its usefulness is further enhanced 

 by the fact that it can be run on either 

 gasoline or kerosene. 



The motor may be obtained in two 



sizes of three or five horsepower. In 



each case it is mounted on a small 



wooden stand, as shown, to drive the 



desired machine by a belt. The 



engine is of the 



two-cylinder, two- 



e, air-cooled 



A Money-Making Idea! Grow 

 Potatoes in Window- Boxes 



IN view of the shortage of 

 potatoes and onions in America, 

 and of the difficulty in supplying 

 the demand for table use, the 

 question of seed potatoes is a se- 

 rious one. The following plan has been 

 adopted by some thrifty housewives to in- 

 crease not only their individual supply of 

 potatoes but their pin money accounts as 

 well by providing some for marketing. 



From each batch of potatoes prepared for 

 cooking, a piece from the "rose" end (the 

 end where most of the eyes are) is cut off 



The portable farm motor is run 

 on either gasoline or kerosene 



type, fitted with a high-tension magneto 

 built in the flywheel. It has a standard 

 type carburetor and an integral fuel tank 

 and mufifler. A gallon of gasoline will fur- 

 nish enough power to saw a supply of fire 

 wood that will last for a week, and in an 

 hour sufficient corn can be ground to feed 

 a well-stocked farmyard.
