At the time when the work was interrupted the builders were engaged chiefly on one of the towers, which they had carried up about one hundred and fifty feet. The stones which were used for this tower were very large, and in order to hoist them up the workmen used a monstrous crane, which was reared on the summit of it. This crane was made of timbers rising obliquely from a revolving platform in the centre, and meeting in a point which projected beyond the wall in such a manner that a chain from the end of it, hanging freely, would descend to the ground. The stones which were to go up were then fastened to this chain, and hoisted up by machinery. When they were raised high enough, that is, just above the edge of the wall, the whole crane was turned round upon its platform, in such a manner as to bring the stone in over the wall; and then it was let down into the place which had been prepared to receive it.

When the work on the cathedral was suspended on account of the want of funds, the men left this crane on the top of the tower, because they hoped to be able to resume the work again before long. But years and generations passed, and the prospect did not mend; and at last the old crane, which in its lofty position was exposed to all the storms and tempests of the sky, of course began gradually to decay. It is true it was protected as much as possible by a sort of casing made around it, to shelter it from the weather; but notwithstanding this, in the course of several centuries it became so unsound that there began to be danger that it might fall. The authorities of the town, therefore, decided to take it down, intending to postpone putting up a new one until the work of finishing the cathedral should be resumed, if indeed it ever should be resumed.

The people of the town were very sorry to see the crane taken down. It had stood there, like a leaning spire, upon the top of the cathedral, from their earliest childhood, and from the earliest childhood, in fact, of their fathers and grandfathers before them. Besides, the taking down of the crane seemed to be, in some sense, an indication that the thought of ever finishing the cathedral was abandoned. This made them still more uneasy, and a short time afterwards a tremendous thunder storm occurred, and this the people considered as an expression of the displeasure of Heaven at the impiety of forsaking such a work, and as a warning to them to put up the crane again. So a new crane was made, and mounted on the tower as before, and being encased and enclosed like the other, it had at a distance the appearance of a leaning spire, and it was this which had attracted Rollo's attention in his approach to Cologne.

Within a few years, on account of the opening again of the navigation of the Rhine, and other causes, the city of Cologne, with all the surrounding country, has been returning to its former prosperity, and the plan of finishing the cathedral has been resumed. The government of Prussia takes a great interest in the undertaking, and the kings and princes of other countries in Germany make contributions to it. A society has been organized, too, to collect funds for this purpose all over Europe. More than a million of dollars have already been raised, and the work of completing the cathedral has been resumed in good earnest, and is now rapidly going on.

All this Rollo's fellow-traveller attempted to explain to him; but as he spoke in German, Rollo did not understand him.

When Mr. George and Rollo reached their hotel, and had got fairly established in their room, Mr. George took his cane and prepared to "go exploring," as he called it.

"Well, Rollo," said he, "what shall we go to see first?"

"I want to go and see the cathedral," replied Rollo.

"The cathedral?" said Mr. George. "I am surprised at that. You don't usually care much about churches."

"But this does not look much like a church," said Rollo. "I saw the end of it as we came into the town. It looks like a range of cliffs rising high into the air, with grass and bushes growing on the top of them, and wolves and bears reaching out their heads and looking down."
