other objects; among these arms were a great number of arrow 
heads of flint, such as I had seen among the Tuscaroras ; farther, 
a great number of toys, and other trifles; a skeleton of the mas¬ 
todon, but not so complete as the one in Philadelphia, forms 
part of this museum; the large teeth are missing, but the lower 
jaw bone* is particularly well preserved; two weeks previous to 
my visit it had fallen down along with the chain by which it 
had been suspended from the ceiling, and had broken in two. 
There is also here, a very handsome collection of minerals. 
It is to be regretted that so many rare things are not better 
arranged, and separated from mere trifles. The city library was 
founded by subscription; it contains about fifteen thousand 
volumes; I asked to see Humboldt’s splendid work on Mexico; 
the library does not contain any thing very remarkable. Mr. 
Thomas, a Friend, one of the philanthropic public characters to 
whom I was introduced by Mr. Vaux, of Philadelphia, conducted 
me to a steam-mill, situated near the basin. It seems to me that 
such a mill is well worth imitating, especially in Flanders, 
where running water is so scarce. The machine which moves 
the wheels was made by Bolton and Watt, of Soho, in England, 
and is of sixty horse-power. r Jfhis mill has eight pair of stones, 
of which there are commonly but four worked at a time; most of 
the work, which in general is done by men, is performed by 
machinery connected with the steam-engine; a long and hori¬ 
zontal chest leads from the interior of the mill to the wharf, 
where the vessels with grain lie; from the vessel, the wheat 
is poured in one of the extremities of the chest, or rather channel, 
along whose whole length a spiral screw runs, which by turning 
brings the grain to a large reservoir in the mill. By another 
piece of machinery the wheat is conveyed to the upper part of 
the house and thrown into a wire cylinder, where it is perfectly 
fanned, and is thence conducted to the hoppers; the flour falls 
into a common reservoir, whence it is conveyed to a bolting ma¬ 
chine. The fine flour passes through a trough to a place where 
it is spread by a horizontally revolving rake, to be cooled; after 
this it runs by a spout to the ground floor, where it is packed in 
oaken barrels. A workman fills the barrel with a shovel, pushes 
it on an iron ring forming part of a scale, to weigh it, underneath 
a wooden block, which acted upon by a lever presses the flour into 
the barrel; this block, after being sponged in the common way, is 
again ready for immediate use. Two hundred barrels of superfine 
* [This is the only perfect lower jaw of the mastodon ever found, and the 
lover of Natural History must regret the extreme carelessness of the proprie¬ 
tor or superintendent of the Baltimore Museum, which has allowed so valuable 
a specimen to be mutilated. The London Medical Society was once in treaty 
for this jaw bone, at the price of three hundred guineas,]— Trans.
