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.

v Rain water pipe 

 An old drain pipe on a garage floor to remove 

 poisonous gases from the automobile engine 



One owner of a private garage avoided the 

 necessity of keeping the doors open by 

 piping the exhaust outside, as shown in 

 the illustration. An old drain pipe was 

 used for the purpose. It was connected 

 in such a way that when the automobile 

 was backed into the garage the end of the 

 exhaust pipe entered the end of the drain 

 pipe. This led down to the floor, where a 

 long piece ran through the wall to the out- 

 side and carried all unpleasant or dangerous 

 fumes to the outside, leaving the interior 

 free from the poisonous carbon monoxide 

 gas. — P. P. Avery. 



Edging Flower Beds with 

 Old Bottles 



VARIOUS methods are used to con- 

 struct edging for flower beds that will 

 produce an effect in keeping with surround- 

 ings. One simple way is to use a number of 



The edging around a flower bed made up 

 of bottles buried part way in the ground . 



bottles, all the same size, set with their 

 necks in the ground, outlining the shape 

 of the bed. Bottles of different colors may 

 be used, or alternate ones let into the 

 ground deeper, making two levels for the 

 bottoms, which have become the tops, 

 similar to a paling fence. 



Flat bottles, shaped on the order of a 

 flask, can be set in zigzag fashion, or like 

 shingles on the siding of a house, to present 

 a very pleasing appearance as a border for 

 a small bed. — Louis M. Wahrer. 



Repairing a Broken Test Tube 

 or Beaker 



WHEN you have broken the top of a 

 test-tube or beaker, do not throw it 

 away, for there is a simple way to cut it 

 off smoothly and make a new lip on it. 



Take a three-cornered file and heat the 

 small end that goes into the handle. Now 

 place the red-hot file on a spot below the 

 break, which has been dipped in water, 

 and hold it there until a slight snap is 

 heard. Now lift the file off. You will see 

 a tiny crack Y% in. long. Reheat the file 

 and repeat the operation, following the 

 crack around in a circle. The broken 

 part can be lifted off and a clean-cut rim 

 is the result. To make a flare, rotate the 

 test-tube or beaker over a Bunsen flame 

 until the glass commences to soften, then 

 with a charcoal block, still rotating the 

 tube, press the edges out. 



In a similar way a lip can be made by 

 pressing down with one edge of the char- 

 coal block. The hardest part of the work 

 is to get the crack started. Sometimes 

 filing starts it. — Malcolm Macurda.
