No. 2 (1921) REMARKS ON CANNING 45 



tightly on the mouth of the jar, when the cap is at once screwed 

 home. • 



21. It is obvious that while wide-mouthed jars can be used with 

 great advantage in packing and removing the contents, there is 

 greater risk of failure of vacuum or access of air than when the 

 mouth is comparatively narrow. Still, very wide-mouthed jars, 

 tumblers, bowls, etc., are in general use. These jars, under 

 various patents, are excellently adapted for domestic use, since 

 they can be used indefinitely often, while the work of fruit canning 

 in such jars is simple to a degree ; in petty domestic manufacture 

 the personal care of an intelligent housewife prevents appreciable 

 breakage or loss of contents. These glass containers have not 

 been used in the Government Cannery not because of the difficulties 

 in their use but because such jars have not been obtainable ; even 

 in pre-war days they were comparatively expensive, and from 

 1914 British jars have been wholly unattainable at any price. 

 Indian-made screw top jars have been offered but without their 

 screw tops and at prices for the empty jars almost as high as 

 would have to be charged for the capped and filled jars when 

 issued from the cannery. Glazed stoneware jars can be similarly 

 used if provided with proper caps, but are even heavier than glass 

 and hardly, if at all, procurable in India, partly owing to the cost 

 of freight, while Indian-made goods of this class if procurable at 

 all — which is seldom — are poor in quality and absurdly high 

 priced.
