"She is as innocent as a flower! I will not believe she could do such a thing! But she is in trouble." They were regarded with some surprise as they dashed along the streets. The citizens wondered why two boys were riding at such speed. A sleepy policeman shouted at them, but they gave him no heed. Soon they came to the outskirts of the city. Before them lay the lake road. "This is the way they came?" questioned Frank. "Sure," nodded Bart. "They are somewhere ahead." "What makes you think they are skipping the city? It strikes me they may be simply out for a canter. Perhaps they are going to take a look at Tahoe up there among the mountains." "They did not buy horses for a canter of a few hours." "They bought horses?" "Yes." "Then it is pretty certain they have no notion of coming back to Carson. You have a level head, my boy. Forward!" The road became rugged and steep. They were looking for a mounted man and girl in advance, and they constantly urged forward their sweating horses. "I do not see anything of them." "The road crooks away up yonder, so they would be hidden. They have quite a start, and they are in a hurry." A cloud of dust rose behind the galloping horses, drifting away to the left. The road was rough, but the boys did not mind that. "Tahoe must be on the top of a mountain," grumbled Bart, after a time. "It is six thousand, two hundred and eight feet above the level of the sea," said Frank. "That is elevated somewhat." "I should say so. It must be the highest body of water in this country, if not in the world." "It is higher than the peaks of many lofty mountains." "And this so-called 'lake road' is hardly better than an ordinary trail. We are in for a hard pull of it." "But the ones we are pursuing are in for just as hard a pull." "That's right, and one of them is a girl." The mountains loomed formidably before them. The bleak heights seemed to block their way. But the road wound onward and upward, and they followed it. "What was that?" questioned Frank. "What? I did not hear anything." "It sounded like a cry. There it is again." "I heard it that time. It did not seem to be ahead of us, and so it---- Great Scott! Look back!" Frank looked back down the road. Far away, several horsemen were riding toward them. They were urging forward their animals, and the sunlight glinted on polished weapons. "We are pursued, partner!" said Frank, grimly. "We are in for a hot chase." CHAPTER XL. ELUDED. "Who are our pursuers?" asked Bart, angrily. "What do they want? They are shouting and waving their hands." "They are shouting for us to stop. They want me." "For what?" "Have you forgotten, as soon as this, what I told you about the queer money I tried to get changed at the bank?" "Think that is why they are after you, eh?" "Without a doubt?" "Then they must be officers." "It is certain that at least one of them is an officer. The others he may have called to his aid hastily."
