652 MINERALS YEARBOOK

 The statistics in the 5-year table that follows, as well as those reported
for earlier years in Mineral Resources, do not make a precise comparison
between States or years. It always has been impossible to obtain from producers
uniform reports on the quantity and value of their crude material, as they
sell a large part of the product in a prepared or manufactured form. An attempt
made in 1931 to acquire information on the yearly sales of tripoli for distinct
purposes failed completely; only three producers could supply the data requested.
The values given as "sold" are the gross returns, as reported by producers,
and include receipts from sales of both crude and ground (or otherwise finished)
material.
