Practical Hints 



may be, where k wfll do the most good and be less liable to break the glass. 

 If the above method is not effective k is better to let the sash dry out naturally, 

 and if the sticking be of frequent occurrence to have the sash unshipped and the 

 binding edges reduced slightly wkh a plane. 



There are several stupid ways of putting on the outside or "storm" sash, the 

 worst of which is to carry k up a ladder and screw k on from the outside. If you 

 don't object to falling several stories and wearing the sash for a ruff, try k; k k 

 solid and right when once in place, be that on the window or the neck. A better 

 and easier way is to get good stout screw eyes of a size which wfll admit a fair-sized 

 screw through the eye up to the head. In the case of an ordinary sized window 

 three on a side are sufficient. They should be placed in the inner edge of the 

 outside casing, one in the middle and the other two about 4' or 5* from the 

 head and window sill respectively. A small but strong ring screw should be 

 placed on the inside edge of the window munrin, near the centre of the window. 

 The ring of the screw should be amply large to allow the finger to pass through 

 k, as k is used to hold the sash in place while k is being hung. Holes should 

 be bored in the sash to correspond to the screw eyes, so that the screws wfll turn 

 into place easily. The sash is then put through from the inside and the foot 

 brought to a bearing on the window sill; wkh a finger of the left hand through 

 the screw ring; the window is then brought into its proper place. The screws 

 are then readily driven home through the screw eyes, the two middle ones first, 

 thus holding k so that both hands can be used for the placing of the others. It 

 will readily be seen that this method is easy of 

 adjustment by one person, and that the sash is* 

 drawn tightly against the casing. 



Waste. Do not turn house waste into a bund 

 drain, as the stones are soon choked wkh grease and 

 other matter which filter into k. A drain pipe should 

 be used for this purpose. 



Water. Most water is incapable of corrosive 

 action on lead, owing to its lack of absolute purky. 

 Owing to the abundance of nitrates in well water 

 its action on lead is more active, than that of some 

 other sorts of water. 



In arranging for the piping of a house the kind 

 used should be determined by the effect that the 

 water has upon k. This test should be made by a 

 competent expert. 



To protect the lead pipe from corrosion by the 

 action of water, there are several authorities who 



suggest the introduction of dilute chemical solution into the pipes to form a pro- 

 tecting lining. One of these uses sulphite of potassium, in a solution of one 

 pound of sulphke to two gallons of water, and allows k to stay in the pipe 



twelve hours. 



A column of water 12* high exerts a downward pressure of .43 pound to 

 die square inch. To find the pressure in pounds per square inch exerted by a
