A New Can for Handling Gasoline 

 to Prevent Waste 



MUCH gasoline is wasted every year 

 by evaporation and spilling. Now a 

 Chicago firm has introduced a new can 

 designed to prevent

this waste. It is 

 fitted with a hinged 

 spout cover, closed 

 by a spring. This 

 seals the spout the 

 moment the pres- 

 sure of the thumb 

 on the lever is re- 

 leased, thus pre- 

 venting evaporation and 

 also loss by splashing out or 

 spilling. A steady stream 

 is assured when pouring by 

 a long pipe that extends to 

 the bottom of the can, thus 

 admitting air in a steady, 

 constant stream, instead of 

 forcing it to bubble through 

 the stream of gasoline as it 

 leaves the can. This does 

 away with all the objection- 

 able splashing when pouring 

 out the contents of the can. 

 If all the automobile 

 owners in the United States 

 saved one gallon a year each 

 they would create an additional supply of 

 4,500,000 gallons. This is enough to keep 

 1,250 airplanes in fuel for a whole year. 

 It is the team-work that will count in 

 this as in all else. It is the "long pull, 

 the strong pull, and all pull together."

It Walks Through the Field, and 

 Drags a Plow 



THE tractor here shown is a small, 

 inexpensive one that can be used 

 very profitably on farms of less than one- 

 hundred acres. The little 

 mechanical worker is only 

 four feet high and three and 

 a half feet wide, but it v/ill 

 plow four acres a day with a 

 fuel consumption of less 

 than two gallons an acre. 



The tractor is the inven- 

 tion of Rush Hamilton, a 

 California orchardist, who 

 sought in vain for a machine 

 to do his work. It may be 

 called a walking tractor in 

 comparison with the creep- 

 er or round-wheel types. 

 Note the radial tread legs 

 on the wheels. They pene- 

 trate to the sub-soil for 

 traction. 



In plowing, one wheel of 

 the tractor follows in the 

 furrow, thus eliminating the 

 side-draft on both tractor 

 and plow or other imple- 

 ment. The machine is so 

 small that it can pass under 

 the branches of trees where 

 even a horse could not go, much less one 

 of the cumbersome juggernauts which 

 most tractors resemble. It also takes 

 up very little room to store when not 

 in use, and is simple enough to be easily 

 repaired by an amateur mechanic. 



This little tractor is only four feet high and three and a half wide, but it will do the work 

 of four horses. It was invented by a Californian fruit rancher for his own use
