TO STOP A LEAK. 



Leaks in heating pipes sometimes occur at a time 

 when fires cannot be dispensed with long enough to 

 repair them permanently. If these leaks are found to 

 be caused by a flaw in the pipe, or by an opening seam, 

 they can be controlled temporarily in the following 

 manner: Mix fine sand with white lead until it is of 

 the consistency of putty ; spread this half an inch thick 

 on a strip of canvas, long and wide enough to cover the 

 rent ; if possible shut off the pressure of steam, or flow 

 of water; apply the cement and canvas to the pipe, and 

 bind it securely with a canvas bandage. When this is 

 accomplished take some strong cord, commence at one 

 end winding tight and close, until the whole surface is 

 firmly covered with the cord. Great damage can often 

 be prevented in this way, especially when cast iron pipe 

 fails at a season of the year at which permanent repairs 

 are impossible. 



Should a seam open in a steam pipe which is re- 

 quired to resist several pounds of pressure, and at a 

 time when permanent repairs cannot be made, split a 

 piece of rubber hose and lay it over the seam. Cover 

 this with a semi-circular piece of iron that will fit the 

 pipe closely. Fasten all to the pipe by means of clamps 

 similar to those used to fasten wood work to the axle-
