As we have said, the plan for the San Diego work was to build a dam across the canon, and keep the waters from flowing away.

The engineers thought that if they could only take this huge mass of rocky hill and drop it into the canon, it would make their work very much easier, as the task of getting enough stone down to the bottom of the gorge to build their dam was by no means an easy one.

They thought the matter out, and finally decided to try and move the mountain-side into the canon.

They laid their plans, and for two months were busy preparing for the great move.

They tunnelled the hillside in all directions over the section which they desired to move, and in these tunnels laid mines of giant powder or dynamite.

These mines they connected with electric wires, and when all was ready, the various wires were gathered into one bunch, and taken across the gorge that was to be filled up.

When the explosion was about to take place the workmen and engineers moved ever so far away, until they were at a safe distance from the explosion, and one man, the foreman, was sent to the edge of the canon to touch the wires, and start the firing of the mines.

When he received the signal he touched the wire, and then ran away to safety as fast as he could go, while the others watched the explosion.

It seems to have been a most wonderful sight.

Bowlders and masses of rock rose from their beds on the hillside, and little tongues of dust and smoke shot out from the earth in all directions.  Then there was a terrific growl, which seemed to come from the heart of the mountain, the earth shook, the men who were watching were thrown to the ground, and with a roar and a rattle the side of the mountain moved and began to fall.

There was a shower of stones which continued to fall for over an hour, and the dust was so thick that it was impossible to see; but when it finally cleared, it was found that an enormous slice of the side of the mountain had been blown into the canon below.

The engineers said that one hundred and fifty thousand tons of rock had been moved, and to their great pride they found that it had fallen exactly according to their plans, and had bridged the canon and formed the bulwark for the support of the dam.

The past week has been one of great anxiety for Greece and the Greek cause.

The Turks have been steadily gaining ground in the East; they have swarmed through the pass of Milouna into the plains of Thessaly.

The Greeks fought nobly, and succeeded in driving the Turks a little way back toward Milouna, but the vast army of Turkey was too strong for them, and despite their efforts, the enemy has made its way into Greece, and advanced upon the city of Larissa.

The mayors and governors of Thessaly have called on the peasants and all men capable of bearing arms to come to the defence of their country, and volunteers are flocking in every hour.
