 mostly failures, but a sufficient number of 

 cans were saved, and these were of such

 The succeeding years gave essentially the 

 same result. In 1843 he built a small 

 boiler to generate steam and a wooden box 

 in which to put the cans, so that the cooking 

 might be done in a closed steam chamber. 

 As the results were less successful than in 

 the previous years, the steam box was

 for a patent on his method, and it was 

 regarded with so much distrust that the 

 letters were not granted until 1862.

 which underlie the canning of corn. It
