1. The 100th meridian passes through North Dakota about one-third of the way west from the eastern border of the state, passes through South Dakota, Nebraska, Kansas, Oklahoma, and then forms the eastern edge of the Texas Panhandle. The exceptions to this generalization about rainfall are the northwest coastal region about as far south as San Francisco and a few scattered areas in the northwest quarter of the region.
2. In some western states where the dry climate made it impossible for 160 acres to support a farm family, larger homesteads were permitted.

4. The fact that several of the pieces of legislation mentioned in this chapter were passed in 1862 is not a coincidence. Both the opening up of western lands for settlement and the choice of transcontinental rail routes had important implications for the balance of power between free and slave states. Thus, prior to the Civil War, congressional agreement had not been possible. But with southern representatives out of the Congress in 1862, agreement was easily reached.

10. On a long-term loan the sum of the interest payments can be significantly greater than the principal. Thus interest forgiveness of these loans represented a very substantial
subsidy. In point of fact the actual subsidy was even greater than that would suggest because the bureau would not (or politically could not) force the farmer who became delinquent off his or her land.

15. In the east the law has generally relied on riparian rights, a concept derived from English common law, that assigns right on the basis of immediate proximity to the water source. This worked reasonably well in the east but was not practical in the water-short west.

Texas ranked second, also largely on the strength of irrigated land. In the case of Texas, however, irrigation waters largely come from wells in the great Ogallala aquifer. Unlike surface waters that are renewable, "mining" the Ogallala is a one-time event, since the aquifer's recharge rate is only a minuscule fraction of the rate of current withdrawals.
18. The centroid is a calculated point "at which an imaginary flat, weightless and rigid map of the United States would balance if weights of identical value were placed on it so that each weight represented the location of one person on the date of the census." In 1990 the centroid was located a few miles southwest of St. Louis. See ibid., Table 3.

27. Available online at www.census.gov. statab/2012 / 12s0477.pdf. A list of the OMB's estimates of federal tax expenditures may also be found in the Statistical Abstract of the United States. The tax expenditure concept is that a reduction in the amount of tax that would otherwise be collected is an expenditure by another name. Instead of appearing as an expenditure in an appropriations bill it appears as a provision in the tax code. The terms tax break and tax preference are more or less synonymous with the term tax expenditure.
