Through some oversight, an error appeared in the addition of dry hole footage for District A (including 1, 2, 3, and 6) in the table appearing on page 1080 of the Bulletin for 1937. The figure in the right-hand column, opposite A, should be 221,080 instead of 419,795. As a result of this error the total for the column on dry hole footage is also wrong. It should be 3,415,296 instead of 3,614,011. A few other mistakes resulted from this error. Corrections should be made as follows.

In Figure 1, in the parenthesis under the line for "total," just to the right of the map, the figure should be 3,415,296 instead of 3,614,011. Just under this the statement should read "one producer foot for every 9.63 feet dry."

At the right of the map in Figure 2, the statement should read "one producer foot for every 6.80 feet dry."

On page 1080, at the bottom of the column for "Per Cent Producing Footage" the figure should be 9.417 instead of 8.940; and in the next column to the right, for "Per Cent Dry Footage," the figure should be 90.583 instead of 91.060.

In the footnote under the column on page 1080, second line, the figure should be 9.63, instead of 10.31, feet of dry hole.

On page 1081, in the second line of the footnote under the table, the figure should be 6.80 instead of 6.83.

On page 1082, second paragraph, fifth line, the figure should be 3,415,296 instead of 3,614,011. In the same paragraph, third line from the bottom, at the end of the line, the figure should be 9.63 instead of 10.31. In the last line of this paragraph the figure should be 6.80 instead of 6.83.

A quotation was made from this article in the contribution on "Wildcat Drilling in 1937," published in June, 1938. On page 647, Volume 22, of the Bulletin, in the tenth line, the figure should be 6.80 instead of 6.83.
