Horseshoe calks in

Never- Slip Calks Used on 

 Lawn-Mower Wheels 



THE wheels on a campus lawn-mower 

 drawn by a horse became so smooth 

 thai it was impossible to cut long grass 

 with it, because the 

 wheels would slide. 

 The trouble was 

 overcome in a satis- 

 factory manner by 

 using the never-slip 

 calks that are ap- 

 plied to horseshoes. 

 Twelve of the calks 

 were put in the rim 

 of each wheel. The 

 calks are small and 

 will not tear up the 

 turf, and they give 

 plenty of tractive ef- 

 fect for the ordinary cutter reel in long grass. 



Three Methods for Finding a 

 Chosen Card 



FOR this trick the chosen card must be 

 worked to the top of the pack. If it is 

 there already, well and good ; but if not, it 

 must be brought there by some means or 

 other. This is generally an easy matter, 

 even without sleight of hand, and can 

 usually be effected under the pretense of 

 looking through the pack. When the card 

 is once at the top a false shuffle may be 

 given, to throw the onlookers off the track. 

 Then push the top card out sideways 

 beyond the rest of the cards. Let the pack 

 fall on the table. The resistance of the air 

 will cause the top card to turn over and 

 appear face upwards, all the other cards 

 remaining face downwards. 



Another method is as follows: Get the 

 chosen card to the top of the pack. Slightly 

 moisten the first and second fingers of the 

 right hand, and take hold of the pack with 

 the fingers above, thumb below. Jerk the 

 hand containing the pack smartly down- 



wards, at the same time relaxing the 

 fingers, and it will be found that the entire 

 pack falls to the floor, with the exception of 

 the chosen card, which will stick to the 

 moistened fingers. This will be the only 

 card left and the card selected. 



The third method is very similar to the 

 preceding. The chosen card is worked to 

 the bottom of the pack. Moisten the 

 fingers slightly and take hold of the pack 

 with the fingers below, thumb above. 

 With the disengaged hand strike the pack 

 smartly and at the same moment slightly 

 relax your hold on the pack. It will be 

 found that the entire pack will fall to the 

 floor with the exception of the bottom card 

 which adheres to the fingers. 



Making a Push Cart Oil Sprinkler 

 for Dusty Drives 



IN mid-summer when the suburbanite is 

 confronted with dusty driveways and 

 walks, he will appreciate an acquaintance 

 with the home-made oil sprinkler shown in 



An oil barrel swung between a pair of 

 wheels and piped to make a sprinkler device 



the illustration. It consists of a steel 

 frame mounted on wheels, that carries an 

 ordinary oil barrel. Inserted in the bung 

 of the barrel is a short piece of pipe
