“I should think one would land pretty hard,” suggested Grace.

“About the equivalent of jumping from a fence. The descent is very easy, about five hundred feet a minute. However, there will be no need for worry to-day. I am explaining these matters merely as a matter of routine and ordinary prudence. I can imagine no emergency that would make it necessary for you to take the jump into space. If I did, I shouldn’t be taking you up. No, there is no possibility of such a thing. Now, if you will step down we will get you into your flying togs and harness you to the parachute.”

For a moment Grace Harlowe’s courage weakened, but only for a moment.

“If I can go through a battle in the air in an airplane, I surely can ride in a captive balloon, even if the basket I am to ride in does look like a toy spaniel’s sleeping basket,” she told herself. “I am ready, sir,” she announced, stepping down.

A heavy flying coat and helmet were put on, then came the harness. The latter was adjusted while Grace was standing on the ground, the major fixing her up before donning his own harness, examining it with a care that sent the cold chills up and down the spine of J. Elfreda Briggs.

“Does it pinch you anywhere?” asked the major. “You know it must fit firmly.”

“I think it is quite comfortable,” replied Grace. “Now what do I do?”

“Climb up the ladder and get in, being careful that you do not foul the lines.”

The officer stood on the ground to watch her getting in to make certain that the parachute ropes did not become tangled. Grace ran up the ladder nimbly and climbed over into the basket, which was just deep enough to leave her head and shoulders showing above its upper edge.

“All set,” cried the major, going up the ladder. “Let up gently. I’ll direct you as we go as to altitude. You see, Mrs. Gray, we are connected with the truck by a telephone wire, so that the observer may be always in contact not only with his base, but also with the artillery control station. We spot in wartime, both for marks and for results. Sorry I can’t show you some spotting under actual war conditions.”
