sion of the progress and movement of population, 
which is illustrated by numerous colored charts relat- 
ing to the progress of settlement, and the distribution 
of the different elements of the population. Other 
subjects, such as inter-state migration, immigration 
and nativity of the population, and occupations, are 
ably discussed by the late superintendent, Gen. Walk- 
er, in remarks introductory to the tables relating to 
these subjects. The volume is a bulky one, contian- 
ing, with its full index, 1,050 pages. It contains, also, 
forty-two colored maps, of which twenty-eight are dou- 
ble-page maps, and thirty other full-page illustrations. 
The volume upon manufactures, which has but 
recently appeared, is an equally bulky tome, com- 
prising 1,248 pages. ‘The opening discussion, by 
Gen. Walker, is brief, comprising but thirty-five 
pages; and, while it is suggestive rather than ex- 
haustive, it skims the cream from the whole body 
of statistics. The tables present: 1°. General sta- 
tistics regarding manufactures, by states and terri- 
tories, in 1880, 1870, 1860, and 1850; 2°. The statistics 
for the whole country, of certain specified indus- 
tries, some three hundred and fifty in number; 
3°. Similar statistics for each state and territory; 
4°, General statistics by counties; 5°. Statistics re- 
_ garding selected branches of manufactures by coun- 
ties; 6°. The manufactures of a hundred leading 
cities; and 7°. Special statistics regarding certain 
leading industries. The statistical portion of the 
volume occupies four hundred and seventy-six pages. 
The report of Mr. Hollerith upon ‘Power’ consists 
of tables, showing by states the amount of steam 
and of water power in use, and also the power ap- 
plied to certain leading industries in the several 
states. The statistics are prefaced by a few pages of 
discussion, in which the leading points are brought 
out. The report is accompanied by four colored 
charts of the eastern part of the United States, show- 
ing, by shades of color, the total power in use, the 
steam-power, and the water-power, each in proportion 
to area, and the local excess of steam and of water 
power. There are also three sheets of diagrams, 
illustrating the proportions of power in different 
industries and in the several states and territories. 
In his able treatise upon the Factory system of the 
country, Col. Wright sketches the origin and history 
of that system; treats of its evil effects, both moral 
and physical, particularly upon women and children, 
of its influence upon wages, prices, and production; 
and summarizes the legislation of the several states 
in regard to factory operatives. To the houses of 
factory operatives he devotes much attention, illus- 
trating his text with plans and elevations of many 
houses for operatives, selected from foreign and 
American examples. This paper isa very instructive 
one, both economically and socially. The report of 
Mr. Fitch, upon Interchangeable mechanism, treats 
of the manufacture of fire-arms, ammunition, sew- 
ing-machines, locomotives, watches, clocks, and 
agricultural implements. He sketches the history 
and progress of these branches of manufacture in 
this country, and details the most recent improve- 
ments. This report, as well as that by the same 
SCIENCE. 
author upon hardware and cutlery, is fully illustrated 
with cuts. The report upon Iron and steel pro- 
duction, by James M. Swank, secretary of the Amer- 
ican iron and steel association, is here reprinted. It 
was first issued by the census office as a separate 
publication, being the first complete report published 
by that office. Mr. Swank precedes the statistics of 
production by a very full discussion, and closes the 
report with an extremely interesting and valuable 
history of the iron and steel industry, not only in 
this country, but in the civilized world; beginning 
with Tubal Cain, in the seventh generation after 
Adam. The report is illustrated with six double- — 
page charts, showing the iron-producing regions of 
the country, and the production, by counties, of pig- 
iron, rolled iron, wrought-iron blooms, and steel. 
The report upon Silk manufacture, by Mr. Wyckoff, 
consists of a summary of its history, and a very full 
sketch of its present condition in this country. That 
upon Cotton manufacture, by Mr. Atkinson, is ex- 
tremely brief, comprising only sixteen pages: it 
opens with a summary of the cotton-producing 
countries of the globe, the sources of supply of the 
staple, and goes on to discuss the methods of manu- 
facture, and the relative qualities of the product of 
this and European countries, and the facilities 
offered by different parts of this country for this 
industry. The report of Mr. Bond consists entirely 
of statistics relating to the industry of wool manu- 
factures, prefaced by a few introductory remarks. 
The report upon Chemical products treats of the 
production of soda, manufactured manures, phos- 
phates, sulphur and sulphuric acid, potassium bi- 
chromate, potash, phosphorus, borax, bromine, nitro- 
glycerine, acetate of lime and salt. The volume 
closes with Mr. Weeks’s report upon Glass manufac- 
ture. In addition to full statistics regarding this 
industry, Mr. Weeks summarizes and discusses the 
statistics fully. ‘This portion of the report .is fol- 
lowed by a treatise upon glass, the materials used in 
its manufacture, and the methods employed both in 
manufacture and in working. The report closes with 
a history of the industry from the earliest historic 
times. An admirably full and complete general 
index is given, in addition to the indices to the 
several reports. Probably with a view to a separate 
publication of each special report, each is paged by 
itself on the top, while at the bottom the paging 
runs consecutively through the volume. 
—S. E. Cassino & Co. desire us to state that they 
have bought the interest of Estes & Lauriat in the 
‘Standard natural history,’ and are now the sole pub- 
lishers of that work. 
Mr. J. H. Emerton, whose name was given as a 
contributor to this work, writes that he is only so in 
so far asa part of the chapter on spiders is quoted 
from what he had published elsewhere. 
— La Nature, Dec. 15, 1888, apologizes for an error 
in stating that Mr. Ferry crossed the English Chan- | . 
nel on the water-tricycle figured in Science, Dec. 14, ia 
and gives illustrations of the tricycle, convertible ‘ite : 
a boat, in which the passage was actually made. __ ie
