and a similar process followed as when using glass jars. When the con- 

 tents are cooked, the tins are taken out. the vent soldered up as speedily 

 as possible, and immediately re-placed in the boiler, and kept there for, 

 say, 4 or 5 minutes, after which they are removed and cooled. 



If not properly sterilized, or should there be any leakage, fermentation 

 will set in and in a little while cause the tin to swell or bulge out. Should 

 this be the case, the fruit will of course not keep, but if air-tight, and the 

 process properly carried out. the top and bottom of the can should show 

 a slight hollow rather than a swelling and the fruit will keep indefinitely. 



Pulping. — Pulping is frequently resorted to when, for any reason, it 

 is not convenient to immediately make the fruit into jam. The process 

 is simple, and is accomplished Ijy placing the fruit when prepared into an 

 open vessel with a little \vater sufficient to keep it from burning. Bring

cans and immediately solder down. It may be left in the cans for any 

 length of time till needed for use, and the sugar added when made into 

 jam. Kerosene tins, when properly cleansed, are frequentlv used for hold- 

 ing the pulp ; tliey are a cheap package and answer the purpose very well. 



When preser\'ing in tins, either as. canning or pulping, care should be 

 taken to examine the tins for a few days after the operation is completed. 

 If it is found that there is no depression in the top or sides, it is a true 

 indication. that there is a leakage of air ; in a .short time fermentation will 

 set in and instead of a depression there will be a bulge. In such case it is 

 necessary to puncture a small hole to allow the gas to escape and to re- 

 sterilize the tins and again solder down as before. 



Before using the tins, it is well to find out whether there is a leakage 

 in the tins caused by defective soldering. This is done by pressing the 

 tins, with the mouth dowaiwards. into hot water ; should any leakage occur, 

 the air will escape through the leakage and it may be easily detected. This
