First part to 230° Fahrenheit. This stood an hour without 
erystallizing ; found it too low, although the thumb and finger proof 
indicated otherwise. 
Second part to 246° Fahrenheit ; which was added to the first, and 
in a few minutes crystals began to appear. 
Third part to 238°; being the mean of the other two. On finishing 
this, the two preceding had formed a thick, opaque mass of good 
crystals.

Fifty rows, four feet apart and two hundred and eighteen 
feet long, constitute an acre, and two hundred feet 
of a row is less than one fiftieth part of an acre by 
eighteen feet, therefore add pro rata, 1.03 2.45

A gallon of molasses weighs twelve pounds, therefore, divide 1485 
by 12, and we have, gallons, 123.75.
