It is interesting to note how many things once thought by intelligent people to be impossible, have nevertheless come to pass. It was once demonstrated to the entire satisfaction of mechanical engineers, that no steamboat could ever cross the Atlantic, because the ratio of coal to bulk was thought to be against the distance. Now we have the impossibility of crys-talizing sugar from Indian corn and other things, tolerably well solved. Of this, in a recent address before the Massachusetts Horticultural Society, Hon. Marshall P. Wilder spoke of the possibility of producing sugar in quantity from sorghum on our own soil, in which he fully believed. It has been stated that sorghum sugar cannot be crystallized, but it is now a settled fact that it can.
