The Bulletix. 



There are numerous kinds of glass jars on the market, many of 

 them having certain distinct points of advantage. See Fig. 2. The 

 jar most commonly used is the ordinary screw-top type. See Fig. 2, 

 !N"os. 4 and T. Although they are cheap in price, it is hard to do 

 successful canning in them on account of the difficulty in sealing 

 them air-tight during the processing or cooking. The tops are usually 

 metal with a porcelain lining that sooner or later may become 

 loosened and come out, thereby making the top unsatisfactory for 

 use. Jars of this type can best be used for rich preserves, jams and 

 jellies where complete sterilization is not of so much importance as 

 it is with canned fruits or vegetables. Fig. 2. Xos. 3 and 5, show 

 two jars with improved screw-tops. These jars have a glass or 

 porcelain top which is held in place by a metal band that screws down 

 over the neck of the jar. This is a decided improvement on the 

 old-style screw-top.

Fig. y. Most satisfactory types of jars for general use. 



The most satisfactory types of jars for general use are those 

 shown in Fig. 3. This shows the original '•'Lightning Patent" small- 

 mouth jar with glass top held in place by a wire spring; the "Safety- 

 valve"' type jar with similar top held in place by a lacquered metal 

 band fitted with a spring and lever; and the improved wide-mouth 

 "Lightning Patent" type jar with glass top held in place by a simple 

 wire spring. The "Safety-valve" type jars are used by some com- 

 mercial packers in canning the extra-fancy grades of fruit and vege- 

 tables. The wide mouth of the improved jar is a decided advan- 

 tage when canning whole fruits or vegetables. Although jars of the 

 types illustrated are a little more expensive, much more satisfactory 

 and successful work can be done with them than with those having 

 screw-tops. When buying jars, get as good a grade as can be af- 

 forded. The best quality usually retails at from $1 to $1.25 per 

 dozen. The first expense may be somewhat high, but with reasona- 

 ble care good jars should last many years.
