copper, and when painted and sanded not likely to be affected by 
.moisture. In many foreign countries the roofs are of plaister. 
We are two objections to metal roofs in this country, the high 
price and the great heat in summer. They are much the lightest 
and most durable kind of roof. I am at present of opinion that 
the paper or pasteboard roofs are the most eligible. They might 
be painted with tar and sprinkled with sifted sand, washed ashes, 
or lime. The pasteboard is well sized wit],! glue. They might 
be tanned soon after being made, by infusing in a solution of oak 
bark if necessary, but this would not be. T. C. 
Provisions. The expence of provisioning troops, the frequent 
scarcity of provisions on a march, the neglect and frauds of con- 
tractors, the discontents of ill fed troops, and the delays thus occa- 
sioned, render it of great importance to find some kind of nutri- 
tious food easily transported, and not easily spoiled. I recom- 
mended lately in the Emporium, vol. 2. p. 462, 463, Indian corn 
parched and ground, with bacon or pork and portable soup well 
seasoned. I am glad to find by the papers of this week before 
ihe, that Mr. B. Hawkins, Indian agent for the United States, has 
publicly come forward to propose parched and ground Indian corn. 
The corn parboiled, then gradually baked until it assume a fine 
light brown colour and ground, is eaten with a small quantity of 
tfugar. In a national point of view, this is a subject of very great 
moment, but Mr. Hawkins and I, shall preach in vain. T. C. 
WITH the present number, the present series of the Empo- 
rium closes, for reasons that my publishers will state in the enve- 
lope to this number ; which would have been out in due time, had it 
not been that the printers were serving their country as volunteers. 
My collections on bleaching, dying, calico printing, distilling, 
tanning, pottery, enamelling, glass making, colour making, drug 
making, See. will occupy full two volumes. I shall consider in 
what way they can be best brought before the public, because I 
think it will be doing service to the manufacturing interest, and 
to myself to publish them. T. C.
