thought that it had received no injury, and on the 81st 
of the same month commenced feeding the cattle with 
the tops, cut daily as wanted, except the re-planted, 
which was considered too young: these lasted them ’till 
the 18th September, when the blades were stripped, 
commencing where the topping began, and these _ 
the cattle until the 5th of October. 
In the progress of topping and blading, one row was 
left entire along side of the row topped the 20th August; 
both those rows, and also another row along side of the 
row first mentioned, were all cut off by the roots on the 
2d of October, and hauled in and set up separate, un- 
der my own inspection. ‘They were husked and measur- 
ed on the 8th of November. 
Produce of the row neither topped or stripped 9 5-8 
bushels of corn in the ear. 
Produce of that topped the 20th August and bladed 
20th September, 7 6-8 bushels of corn in the ear. 
And the produce of the one topped the 2d Septem- 
ber and bladed the 20th of same month 7 3-8 bushels 
of corn in the ear. 
This experiment strongly indicates that if all the crop 
had been topped as late as the 2d of September, and 
bladed on the 20th of the same month, that the loss on 
the whole field from those operations would have been 
more than 230 bushels, but as those rows stood near 
where topping and blading commenced, it must have 
been less, yet certainly very considerable, for through- 
out the whole field the husks were generally dry and 
open, except on the row which had not been topped or 
stripped : on this they still retained a greenish hue, and
