Before concluding, it is necessary to remind you that all the analyses 

 I have given are perforce only approximate. The varying com- 

 position of the foods, and the differing assimilations of the recipients 

 render any fixed amounts out of the question. Still, I venture to 

 hope that the information as I have set it forth has not been altogether 

 dreary to you, and if I have aroused your interest and demonstrated 

 the value of your gardens I am amply rewarded.
