“But his company moves, too,” declared Ned, 196 who had made some inquiries. “He’s in the same division we are, and we’ll see him when we get settled again.”

But they did not see Noddy Nixon again for some time, though they heard of him, and under tragic circumstances.

The guess the boys had made about a great offensive was a correct one. The time had come for the turning point in the war, and the backward movement of the British and French was about to stop. The American forces were increasing, and now General Foch was able to put into practice the strategy he had so long waited for. He could attack, and with great hope of succeeding. The turning point had been reached.

There were rumors and all sorts of stories floating around the camp. Ned, Bob and Jerry had been moved to the north and farther toward the great Hindenburg line which was so soon to be pierced, impregnable though the Germans boasted it.

Professor Snodgrass, too, managed, by means of some influence he possessed, to be allowed to accompany that part of the army to which his young friends were attached. He had not ceased his efforts to locate the two girls, but he realized, as did Jerry and his chums, that it was an almost hopeless proceeding now. However, there was still the study of explosive noises on insects to 197 which the professor could devote himself, and he did.

The boys noted, however, that the strain of his uncertain financial situation was telling on the little man. Cheerful as always, and seemingly oblivious to practical affairs, yet there was at times a strained look about his eyes.

“Yes,” he said one day in answer to a question Jerry put, “I have enough for my immediate needs. If I do not get back what I lent to my old friend—and I may even lose more, as I endorsed a note for him to cover a loan from another—and if I cannot use what Professor Petersen left me, I shall have before long to give up my work here, however. And, of course, the trip to the Amazon and the investigations there must be given up.”

“I am sorry, Professor. Can’t we––” began Jerry.

“Tut, tut!” interrupted Professor Snodgrass, with a kindly smile. “We’ll no doubt find the girls—I hope so for their sake as well as my own—and perhaps my friend may be able to adjust his affairs, though I fear––Poor man, poor Albert! It will be a dreadful thing for him to lose all he has and be compelled to start the world over again at his age.” And Professor Snodgrass walked away, his personal trouble forgotten in sympathy with his friend, the very man who 198 was the cause of his own anxieties and probable losses.

Vast were the preparations that went on for the advance against the enemy. Never was there such a collection of cannon, large and small. Never was there such a store of powder and shell. The back lines were like a hundred arsenals turned into one. Food, too, there was in great quantities, for it has been well said that an army fights on its stomach, and there must be no lack of nourishment when the troops went forward, as they were destined to do.
