Then a sudden rage filled the stalwart American. He loved Stanley, who he knew was game to the core. Just then a German machine sped by full tilt, sending spatters of bullets right and left. Instantly Blaine tried the tail-dip, always risky yet worth while if successful. Doubling under the tail of the passing Boches — there were two of' them in the machine — Blaine came up right under the German's propeller, his own gun in straight line for the center of the other's fuselage. As he came up he began a spatter of bullets that fairly riddled the body of the big Taube, and directly thereafter came a burst of flame so bright and searching that Blaine had to dip again, sidewise to avoid its scorching significance. The German's tank was exploding and in a mass of flames the two men fell, the skeleton of their machine about them as the whole dropped to the earth.

Hardly had Blaine cleared this aerial ruin than came the commander's signal to retire. Somehow, after that, Lafe felt that in a measure he had a certain revenge from the Boches for poor Stanley's death; for Stanley was dead — no doubt of that. At least so Blaine thought.

Up he mounted and presently saw Buck Bangs engaged with a rather clumsy German, who seemed bent upon peppering Bangs and his machine full of holes. He flew to Buck's assistance, when the German straightened out and made for his own rear, with Bangs in full pursuit. In his present mood, instead of returning with the rest of the home squadron, Blaine took after the German, and for five minutes there was a mid-heaven race towards Belgium. But Bangs, in his small scout, was easily the fastest and soon he and the German were engaged in a running duel.

All at once Buck signaled to Blaine in code:

"Leave this Boche to me. There's a train off eastward. See if you can't do something. Get up higher: you'll see better."

Mutely Blaine obeyed and, as he rose up another thousand feet, he saw more than one row of cars, upon a single track hurrying towards the front, whence already the distant bellow of earthly struggles was going on. Evidently the big Allied offensive was on. If he, Blaine, could hinder the troop trains from reaching the front trenches, it might be a big help to the infantry, that was now attempting its part of the big stunt.

Straightway the biplane, with the body of Stanley still nestling in the bottom of the observer's, manhole, was shooting downward in a gradual slant towards the two trains. One of these was filled with soldiers, at least a brigade, for the train was a long one. The one ahead seemed to be loaded with munitions and with artillery on the rear cars.

Swooping down closer, Blaine laid his plan. When within three hundred feet he saw some Archies posted at a crossroads who at once began firing. In his present mood he would have cared little for any obstacle as yet untried.

Above the noise of his propellers he detected something behind, and, turning, what was his amazement to see Stanley's ashen gray face peering up over the observer's seat. Blaine was startled, as if he looked at a ghost.

"Get down, boy!" he adjured. "You ain't strong enough. Get down!
I've got a stiff job just ahead. Give me time and room."
