A Modern Reminder 



Instead of knotting a string about the 

 finger to prevent the forgetting of an im- 

 portant duty, several initials may be 

 written in ink on the face of a watch. 

 Each time the watch is consulted, the 

 memory is stimulated sufficiently by the 

 initials so that the particular duty will 

 not be easily forgotten.

To Pour Acid Safely from Carboys 



The danger involved in pouring sul- 



phuric acid from a carboy can be avoided 

 if a bent glass tube is inserted into the 

 neck of the bottle so that the partial 

 vacuum caused by the liquid gushing out 

 is equalized.

A Brush Holder 



It is often necessary to lay aside a 

 brush during a painting job and if it is 

 placed in the can there is a possibility 

 of its becoming entirely covered with 

 paint, which is obviously unpleasant. In 

 order to eliminate this trouble, a screw 

 hook or bent nail can be placed in the 



handle of a brush, as shown in the sketch. 

 Thus, when the brush is not required 

 for the moment, it may be placed in the 

 can without danger of its becoming en- 

 tirely covered with paint.

Bent Spring Holds Door Ajar 



A handy catch for the door, which 

 will prevent its being blown shut when 

 ajar, can be made from stiff brass or 

 steel wire of 10 or 12 gauge.
