Mr. GODFREY. You will notice that we have gone right up to 40 million acres with almost a continuous rise.

Here is a chart we hear quite a bit about, tree planting and timber stand improvement.

We have been trying to emphasize this a little in the last few years. We think that, living in a paper economy, this is important from this standpoint, if no other. I should say we have increased participation on timber stand improvement from 1936 through 1960 and we have a little better than 5.3 million acres in tree planting and improvement. This is graphically illustrated by a decided upswing in the last few years when emphasis has been placed on long-term and enduring practices.

Next we have a chart on acreage terraced.

(The chart referred to follows:)

Mr. GODFREY. This shows a little dropoff in the acres terraced per year. This is not due to the lack of interest on the part of farmers or to the fact we have almost completed the job, but it is due primarily to a change in emphasis in some areas of the country from terracing to vegetative cover, particularly in the southeastern part of the country. Some of our agronomists are now indicating the need is more for retaining the water where it falls, rather than building terraces to hold it and permit it to flow off evenly. You will note we have accomplished quite a bit and in another 15 or 25 years will have 23 million acres actually terraced.

The next chart has to do with permanent sod waterways to control erosion and dispose of runoff.

PERMANENT SOD WATERWAYS TO CONTROL EROSION AND

Mr. GODFREY. That runs to about 670,000 acres for the period and we have only records from 1940 to 1960. We did not have this practice listed as such in the program from 1936 through 1940. You will note that there has been a continuing increase.

The next chart has to do with water storage reservoirs and you will notice we have constructed about 1,650,000 from the period 1936 through 1960.
