Trade and Commerce.—The manufactures of Iowa are chiefly such as have to do with the products of the farm. Meat packing is the most important, the product of this industry amounting in 1900 to $25,695,044, and in 1905 to $30,074,070, an increase of 17% in this period; in 1900 the state was seventh, in 1905 sixth, among the states in the value of this industry, producing in each year 3.3% of the total. Next in importance is the manufacture of dairy products, the value of which in 1900 was $15,846,077 (an increase of 50.3% in ten years) and in 1905 was $15,028,326; at both censuses the state ranked third in the value of cheese, butter, and condensed milk and of food preparations, which were valued at $6,934,724 in 1905. Flour and grist-mill products ranked third both in 1900 and 1905, the value of the product for the later year being $12,099,493, an increase of 9.9% over the value for the earlier. Among the lesser manufactures are lumber and timber products (value in 1905, $5,610,772), most of the raw material being floated down on rafts from Wisconsin and Minnesota. The largest centres of industry are Sioux City, Davenport, Dubuque, Des Moines, Burlington and Council Bluffs. In 1905 the gross value of the manufactured product (of establishments on the factory system) was $160,572,313, as against $132,870,865 in 1900, an increase of 20.8%; whereas, even including the products of smaller establishments not technically factories, the value of the product in 1850 was only $3,551,783, and in 1880 was only $71,045,926.
The means of transportation is afforded chiefly by the steam railways, of which the state had 9,907.44 m. in January 1909. Scarcely a farm is more than 6 or 8 m. from a railway station; and only three other states have a greater railway mileage. The great period of railway building in Iowa was during the twenty-five years immediately following the close of the Civil War, the railway mileage being only 655 m. in 1860. The several roads are under the management of twenty-seven companies, but about 75% of the business is done by the Chicago Burlington & Quincy, the Chicago & North-Western, the Chicago Milwaukee & St Paul and the Chicago Rock Island & Pacific. Electric interurban railways are increasing in importance for freight and passenger service. In 1908 about 225 m. of such railways were in operation. Transportation facilities by water are afforded by the Mississippi river. The former difficulties with the Des Moines Rapids of the Mississippi (which are passable for rafts and light boats at high water) have been overcome by a canal from Keokuk to Montrose constructed by the National Government. Other federal improvements undertaken are a harbour at Muscatine, a harbour of refuge below Davenport and channel improvements at Clinton.
Population.—The population of Iowa in 1850 was 192,214; in 1860, 674,913; in 1880, 1,624,615; in 1890, 1,911,896; in 1900, 2,231,853. The state census of 1905 showed a total population of 2,210,050, and the Federal census of 1910, of 2,224,771. Of the population in 1905, 1,264,443 (57.2%) were native whites of native parentage, 648,532 (29.3%) were native whites of foreign parentage, 289,296 (12.8%) were foreign-born and 14,832 (0.7%) were coloured, including 346 Indians. The Indians, a remnant of the Sauk and Foxes, are most unprogressive, and are settled on a reservation in Tama county in the east-central section of the state.
In 1906 it was estimated that there were 788,667 communicants of all religious denominations; of these 207,607 were Roman Catholics; 164,329 Methodists; 117,668 Lutherans; 60,081 Presbyterians; 55,948 Disciples of Christ; 44,096 Baptists; 37,061 Congregationalists; 11,681 members of the German Evangelical Synod; and 8990 Protestant Episcopalians.
The rural element of the population is large, though it is not increasing as rapidly as the urban; and no other state in the Union is so uniformly settled. There were in 1905 seven cities with a population of 25,000 or more; twenty with 8000 or more; and thirty-seven with 4000 or more. Between 1890 and 1900 the urban population increased 38.3%, while the rural increased 14.6%. The chief cities are Des Moines (pop. in 1905, 75,626), Dubuque (41,941), Davenport (39,797), Sioux City (40,952), Cedar Rapids (28,759), Council Bluffs (25,231) and Burlington (25,318).
Government.—There is comparatively little in the political institutions of Iowa dissimilar to those of other states of the Union; they show in recent years a tendency toward greater centralization—in boards, however, rather than in individual officers. The constitution now in force was adopted in 1857, the constitution of 1846 having been superseded chiefly on account of its prohibition of banking corporations. The present one admits of amendment by a vote of a majority of the members of both houses of the legislature, followed by a majority vote of the electors in the state voting on the amendment; and by this process it was amended in 1868, 1880, 1884 and 1904. The present constitution also provides that the question, “Shall there be a convention to revise the constitution and amend the same?” shall be submitted to the people once every ten years (beginning with 1870), but the affirmative vote taken in accordance with this provision has hitherto been small. The suffrage now belongs to all male citizens of the United States at least twenty-one years of age who shall have resided in the state for six months, and in some one county sixty days preceding an election, except idiots and persons insane or convicted of some infamous crime. The franchise was conferred on negroes by an amendment adopted in 1868. Prior to 1904 elections were annual, but by an amendment of that year they became biennial.
The central executive and administrative authority is vested in a governor, a lieutenant-governor, an executive council, several boards and a few other officers. The governor and the lieutenant-governor was elected for a term of two years, and the qualifications for both offices require that the incumbents shall be at least thirty years of age and shall have been for two years immediately before their election residents of the state. Under the Territorial government when first organized the governor was given an extensive appointing power, as well as the right of an absolute veto on all legislation, but this speedily resulted in such friction between him and the legislature that Congress was petitioned for his removal, with the outcome that the office has since been much restricted in its appointing power, and the veto has been subjected to the ordinary United States limit, i.e. it may be overridden by a two-thirds vote of both houses of the legislature. Members of boards of regents or trustees of state institutions are for the most part elected by the General Assembly; railway commissioners are elected by the state electors; while in the case of the few appointments left for the governor, the recommendation or approval of the executive council, a branch of the legislature, or of some board, is usually required. He, however, is himself a member of the executive council as well as of some important boards or commissions, and it is in such capacity that he often has the greatest opportunity to exert power and influence. His salary is $5000 per annum (with $600 for house rent and $800 as a member of the executive council). The executive council, composed of the governor, secretary of state, auditor of state and treasurer of state, all elected by the people for a term of two years, has extensive powers. It supervises and audits the accounts of state departments, directs the taking of the census, transfers cities from one class to another in accordance with census returns, constitutes the board for canvassing election returns, classifies railways, assesses railway and other companies, constitutes the state board of equalization for adjusting property valuations between the several counties for taxing purposes, supervises the incorporation of building and loan associations, appoints the board of examiners of mine inspectors and has many other powers. Among other state boards the more important are the board of railroad commissioners, the board of control of state institutions, the board of health, and the board of educational examiners.
The state legislature, or General Assembly, composed of a senate and a house of representatives, sits biennially at Des Moines. Senators are elected for a term of four years, one from each of fifty senatorial districts, the term of one-half expiring every two years. Senators must be at least twenty-five years of age and residents of the state for one year at the time of election. Representatives are elected for a term of two years, one from each of the ninety-nine counties, with an additional one from each of the counties (not exceeding nine) having the largest population; the ratio of representation and the apportionment of the additional representatives from the larger counties is fixed by the General Assembly. The qualifications for representatives differ from those for electors only in that they must have been residents of the state for one year at the time of election, the disqualification of negroes for sitting in both senate and house having been removed by an amendment adopted in 1880. No bill can pass either house without the assent of a majority of all the members elected to that house; the governor is allowed three days (Sunday excepted) in which to veto a bill.
The state judiciary consists of a supreme court of six judges and a district court of fifty-three judges, from one to four in each of twenty districts. The supreme court has three sessions a year, while each district-court judge is directed to hold at least one session a year in each county of his district, and no two district-court judges may sit together on the same case. The supreme court has appellate jurisdiction in chancery cases only, but may correct errors at law in other cases. The district court has general, original and exclusive jurisdiction in all matters civil, criminal and probate not expressly conferred on an inferior court, and may hear appeals from inferior courts, boards or officers.
For purposes of administration and local government the state is divided into ninety-nine counties, each of which is itself divided into townships that are usually 6 m. square. The township may be divided into school districts and highway districts, but in these matters option has resulted in irregularity. Each county has its own administrative boards and officers; and there are two justices of the peace and two constables for every township. The board of supervisors, consisting of not more than seven members, elected for a term of three years, has the care of county property and the management of county business, including highways and bridges; it fixes the rate of county taxes within prescribed limits, and levies the taxes for state and county purposes. The officers of the township are three trustees, a clerk and an assessor. The trustees are elected for a term of three years, the clerk and assessor for two years. All taxable property of the state, that of corporations for the most part excepted, is assessed by the township assessor.
