Concealed by a lumber pile behind Rosenblatt's shack, with his ear close to a crack between the logs, he had heard the details of the plot.

In the cross tunnel at the back of the cave bags of gunpowder and dynamite were to be hidden.

To this mass a train was to be laid through the cross tunnel to a convenient distance.

At a certain point during the conference Rosenblatt would leave the cave on the pretext of securing a paper left in his cabin.

A pile of brushwood at some distance from the cave would be burning.
