Verification of the Bushel measures. 
The weight of the bushel measure, together with the 
8olbs. of water it should contain, was about 250 lbs. and as 
I could find no balance capable of determining so large a 
weight with sufficient accuracy, I was under the necessity of 
constructing one for this express purpose.
