Letter from Carl Hayden to Governor George W. P. Hunt asking the governor to submit the idea of a national park near the rim of the Grand Canyon to the state legislature during the special session. Hayden mentions the state of Arizona would be charged about $28,800 for the land at $1.25 an acre. W. W. Bass and Bass Camp are also included in the letter.

The determination of the number of businesses operating in Arizona is not a straightforward proposition due to data deficiencies and definitional issues. The best data — from the U.S. Census Bureau — are more than two years old. The Census Bureau data are divided into two series: businesses with employees and nonemployer businesses. Each series is based on administrative records. While neither series is affected by sampling error, both are subject to nonsampling error. Certain industries are excluded from each series.
