[Page 166 cont.]

Wilbur Wright went to Kitty Hawk in the morning and tested our anemometer at the weather bureau station. He found its records at 14 mi. an hr. were 10% greater than the anemometer at the station which in turn gives records too great by 7%. The wind being from the south, nothing has been done today by way of experiments.

Dan Tate came today at this a.m. to assist in experiments, cooking, etc. Machine taken to n.e. side of main hill. Wind n.n.e and light. Machine ready for trying the lateral guidance.

1st Exp. No apparent effect of the lateral twist. Machine dug into the ground in the sand at the end of 150 ft. turning Wilbur Wright a somersault.

[Page 167]

2nd Exp. About 250 ft. Flight steady and even, landing safe. No evident effect (wings not twisted) of twisting the wings. Angle of descent 10 ˝°.

3rd Exp. Left wing caught in sand, right wing went ahead and machine fell safely.

4th Exp. 200 ft angle 9° (10°) straight and steady—acting automatically, i.e. leaving the rudder unchanged. 9 sec.

5th Exp. Machine turned first to the right, then to the left. A control laterally seemed to be satisfactory. Flight 200 ft. angle 9° (10°). Rain. Spratt left at 9:30 taking Mr. Chanute’s camera with him, after taking one picture.

Rain, rain, rain! Dan Tate came down from Kitty Hawk, bringing mail and provisions, but the weather does not admit of experiment. Mosquitoes becoming troublesome.

Day opened clear with good breeze from the south. Dan Tate arrived at 10 a.m. and machine was taken to the large hill west of the main Kill Devil Hill. Buzzards numerous. One sailed over head across the flats without flapping or apparent loss of elevation for a distance of a mile or more. 11 a.m. Clouds—Rain in the direction of Nag’s Head—wind light. 11:30 a.m. Brought the machine back to camp. Rain in the distance.



[16 August 1901 - Edward C. Huffaker Dairy, Kill Devil Hills, NC]

Stiff breeze from the south unsuitable for experiments. Dan Tate brought down the provisions from Elizabeth City, in his boat. Wilbur Wright and I went over and helped carry them over to camp. The strips of sheet iron which I ordered seemed to have been

overlooked in the shipping. It is no great matter. In the afternoon the machine was taken to the top of the main hill where the drift was carefully measured and photographs taken. Data Weight 240 lbs. Angle 66 ˝°. Speed 13 metres per sec. Pull 16 lbs. Rising trend of wind 2°. Afterwards it was taken to the small middle hill and ten or twelve experiments made in hovering. Wind about 9 meters per sec. Machine fell about 2 ft per sec. With an advance of about 10 ft per second. Some trials were also made in the lateral control and it was apparently found that the wing having the greatest angle lagged behind.



[17 August 1901 - Edward C. Huffaker Dairy, Kill Devil Hills, NC]

Wind from the south veering occasionally to the see. Velocity 20 mi. per hr. Made half a dozen experiments on low hill s.e. of camp, taking a number of photographs, but accomplishing little else. The Wrights have about decided to break up camp, ship their goods by boat and leave for home by Nag’s Head. Wed. next 22 Aug.



[18 August 1901 - Edward C. Huffaker Dairy, Kill Devil Hills, NC]

Experiments were terminated yesterday. The Wrights expect to sail on Tuesday or Wednesday. I am now at Nag’s Head. Steam-boat at wharf.
