 value of the produce, and hence has arisen the sayings of, 

 " Worth a miller's thumb ;" and, " An honest miller hath 

 a golden thumb ;"* in reference to the amount of the profit

 the best test for the quality of flour.

 portion of a red worm. M. Kisso says it is eaten in Italy ; 

 and Pallas tells us, that in Russia this fish is used by some 

 as a charm against fever, while others suspend it horizontal! v,
