ten years ending June 30, 1860, the total imports of guano into the 
United States amounted to 842,787 tons; the amount reéxported during 
the same period being 71,788 tons. The imports of 1854 and 1855 were 
exceptionally large, in the former year reaching 175,849 tons, and in 
the latter year 173,961 tons. The following is a statement of the

The import values, of course, represent the cost in the countries from 
which guano is received. The Peruvian Islands have afforded the chiet 
supply ; the British West Indies ranking next in importance as a source 
of supply during the last ten years. During the years 1867~70, besides 
the reéxports above stated, there were also exported 3,755 tons, valued 
at $86,610, the product of territory of the United States; and in the 
years 1869~70 there were received 32,690 tons, valued at $645,717, the 
product of islands, &c., belonging to the United States.. Such quantities 
as were received from like sources in years previous to 1869 were 
merged in official statements of imports. A large proportion of the 
total receipts of the last five years has been absorbed in the manufacture 
of artificial fertilizers, but the use of guano for this purpose is stated to 
be now on the decline. 
Manufacture of bone meal. At the New York Farmers’ Club, in reply 
to inquiries concerning the supply of bones and the manufacture of 
bone meal and flour, Mr. J. B. Lyman stated that in cities, on an average, 
the feeding of 20,000 persons turned out as refuse a ton of raw bones 
daily. Newark, New Jersey, has a population of 110,000, and sends six 
tons of bones daily, including heads and heels, from the butchers to a 
large bone-mill two miles distant. The bone-mills of our country are 
supplied from the large cities, and the bone refuse of 35,000,000 of rural 
and town population is lost to the soil. In the cities bones cost $25 to 
$30 per ton. A good plan for a farmer wishing to obtain pure bone 
meal at a cheap rate is to contract with butchers, farmers, and hotel- 
keepers for supplies of raw bones, which should first be boiled for
