From Introduction: "In the present paper, the variation of effective gust velocity in convective-type clouds with altitude is investigated. Data obtained during 1941 and 1942 at altitudes up to 34,000 feet and data obtained more recently from the Thunderstorm Project (reference 5) at altitudes up to 26,000 feet are utilized for this purpose. Consideration is given in analyzing the results both to data for the range

Report discussing a geological examination of an area in Polk County, Florida with leached zones containing uranium. The objective of the study was to determine the advisability of making plans for stockpiling the leached zone material in this area.

The following document contains two reports providing results from reconnaissance missions in Florida. These missions tested the radioactivity in Florida sands and the radioactivity in phosphates and rocks found in Florida.

Revised edition. "Muscadine grapes, which are native to the southeastern part of the United States, thrive in most soils of that region. They can be grown successfully in the Southeastern States, where American bunch grapes do not thrive. furthermore, they are suitable for home gardens as well as for commercial use. In fact they are perhaps the most satisfactory of all fruits for the home garden in this region. They cannot be grown, hoever, where temperatures as low as 0 °F occur habitually and may be injured at somewhat higher temperatures. Muscadine grapes are relatively uninjured by diseases and insects and produce well with a minimum of care, but they resopnd favorably to the good cultural practices recommended in this bulletin. The varieties described or listed produce fruit suitable for making unfermented juice, wine, jelly, and other culinary products and for eating fresh over a long season." -- p. ii

"The turnip aphid is one of the most destructive and widely distributed pests of turnip, mustard, radish, and related crops in the United States. It causes heavy losses to growers of these crops every year, especially in the Southern States. Dust mixtures containing derris, cube, or nicotine, and sprays containing derris or cube, will control the turnip aphid when applied properly. The first application of insecticides should be made when the plants are very small, and additional applications should be made at intervals of 7 to 14 days up to the time of harvest. To provide for effective application of insecticides, the seed of susceptible crops should be planted in drills, with the rows spaced uniformly apart. The following cultural practices aid in the successful production of crops exposed to turnip aphid attack: (1) A well-prepared, fertile seedbed to produce thrifty and rapidly growing plants, (2) planting the seed in drills to permit cultivation, (3) harvesting early to shorten the period of exposure to infestation, (4) destroying crop remnants to eliminate a common sources of infestation to succeeding crops, and (5) applying a nitrogenous fertilizer to stimulate plant growth." -- p. ii

Revised edition. Report discussing best practices for the cultivation of strawberries in the South Atlantic and Gulf Coast regions of the United States. Topics discussed include varieties, soil preparation, mulch and fertilizers, irrigation, harvesting, and diseases and insect enemies.

Revised edition. This bulletin discusses the cattle-fever tick and methods for controlling it. Possible methods include dipping, pasture rotation, and arsenical dips. The life history of the tick is also discussed and instructions for constructing a concrete vat are given.

From Introduction: "Figure 1 shows the location of sources that have been either exploited or seriously considered at one time or another, super-imposed upon a map indicating by small letters the order of consumption of K2O in the leading States; the amount used in these States, together with the percentage of the total consumption of potash used as fertilizer in the United States in 1939, is given in table 1. Figure 2 shows the domestic production and total consumption of potassium salts, in terms of tons of K2O, with the value per unit at the plants, for each year since 1913. Considered together, these two figures tell a significant story."

"The results obtained from an evaluation for gust and draft velocities of acceleration and airspeed-altitude records taken by NACA recording instruments installed in P-61c airplanes participating in thunderstorm flights 6, 7, and 8 of July 9, 1946, July 10, 1946, and July 11, 1946, respectively, are presented herein. These data are summarized in tables I and II. In accordance with a recent discussion with a member of the U.S. Weather Bureau staff, the tabulated results for the present flight include in addition to data of the type presented in reference 1, the initial heading of the airplane for each traverse, the pressure altitude at the start of each traverse in increments of 500 feet, and the gust gradient distance when it could be evaluated" (p. 1).

This report presents the results obtained from gust and draft velocity measurements within thunderstorms for the period August 7, 1946 to August, 13, 1946 at Orlando Florida. In several of the surveys, indications of ambient air temperature were obtained from photo-observer records. These data are summarized in the report.

The results obtained from gust and draft velocity measurements within thunderstorms for the period July 24, 1946 to August 6, 1946 at Orlando, Florida are presented herein. These data are summarized in tables I and II and are of the type presented in reference 1 for previous flights. In two thunderstorm traverses, indications of ambient-air temperature were obtained from photo-observer records. These data are summarized in table III.
