Second Chronicles

Second Chronicle continues the history of Israel from First Chronicles (originally they were one book). It covers a period of almost four centuries, beginning with the reign of Solomon and ending as the Babylonian captivity started.

The chronicles are books of comparisons and contrasts. There was something alike about all the periods when the kings of Israel were successful and the people thrived. Likewise, periods of defeat and loss all shared a common element. These thriving and dying periods similarly were unlike in a key way.

The key factor was the faithfulness of the king, and the people, to God. When the kings sought God and the people worshipped Him, he blessed them and caused to rise in wealth and power. When the king and people sought their own ways, especially to worship the idols and practice the sins of neighboring kingdoms, God let them fall into the hands of their enemies. Eventually, Israel was completely taken over by Babylon.

This pattern could play out even if the reign of a single king. Some hard-hearted kings would start well but stray from God and lead the people away with him. Some evil kings responded to God’s call of repentance and reconciliation, and their turnaround could bring the whole kingdom back to God.

One could argue that the kingdom was at its peak during the reign of Solomon. He built the temple, he reigned in peace, and he stored up great wealth for himself and his kingdom. In spite of his wisdom, he strayed, too. Though he never abandoned the worship of God, he suffered for his sins, suffering he brought onto himself.

Even so, Solomon was the model of a good king. His reign takes up more pages than others in the book. A lot happened during that time, especially the building of the temple. The temple was the symbol of God’s presence with the nation of Israel, and His blessing is central to the prosperity of the nation, so it makes sense that His temple received a lot of attention.

Other notable kings include Jehoshaphat, Hezekiah, and Josiah. These leaders were associated with revivals, the destruction of idols, the restoration of worshipping God, and generally successful reigns. As an engineer, I take special note of Hezekiah, who was famous for building a reservoir and underground aqueduct to supply water to Jerusalem.

The Johnstown Flood by David McCollough

On Memorial Day 1889, a storm struck western Pennsylvania. Floods were common enough in the mountain community of Johnstown and the surrounding villages. This one was extraordinary. Upstream the valley sat a structure that was poised to make the flood much worse, the dam at South Fork Reservoir.

David McCullough describes the flood and the devastating dam break in The Johnstown Flood. It was the worst disaster in the United States up until its time with more than 2,000 people killed by the huge wave that swept down the valley, with more killed by fire and disease in the aftermath.

The dam had originally built by the State of Pennsylvania too supply water for a canal. Within a few years the canal was closed because the railroad provided freight and passenger transportation through the area. The dam changed hands several times after that. I fell into disrepair. Somewhere along the line someone salvaged the pipes that allowed one to control the water level behind the dam; though in it partly collapsed state it no longer held much water.

This changed when developers bought the dam and surrounding property to build a resort for the wealthy industrialists of Pittsburgh. The dam was rebuilt with indifference to materials and methods. The drain pipes were never restored. The spillway was obstructed by a grate (to keep the fish in the stocked lake from disappearing downstream) and low bridge. By the time of the flood, perhaps since it was repaired, there was a slight dip in the center of the dam, creating an unknown, unprotected second spillway. This dip was hard to see with the eye on the large dam, but a survey to measure the elevations would have turned it up.

The dam filled and the lake became quite large. The vacationers sailed ships on it. The water level was commonly within a couple of feet of the spillway, and there was no practical way for the dam operators to control that water level. It was a disaster waiting to happen.

Many of the people of Johnstown expressed concern that the dam was a danger to the city. However, the prevailing view was that the wealthy elite of Pittsburgh would have it built right; very few endeavored to assess it for themselves. Similarly, the members of the South Fork Fishing and Hunting Club, including such prominences as Andrew Carnegie, had faith that the developer did the work right, and they put no effort into checking it out.

When the floodwaters overtopped the earthen dam, it collapsed quickly, unleashing a deadly wave of possibly 20 million tons of water. It is hard to imagine the devastation caused by the wave, even 15 miles downstream in Johnstown. McCullough describes it, sometimes in great detail, based on reports from the time. The rolling wall of water seems awesome at first, but as it begins to destroy homes and injure and kill people, it becomes sickening as well.

The people of that valley recovered with admirable speed and took over the cleanup and restoration of their town the very next day. Soon aid came from across the country, and especially from elsewhere in Pennsylvania, including the National Guard and a still young American Red Cross.

As the initial terror of the event subsided, attention turned to the club at South Fork. Though the press, including the Engineering News, laid blame on the club and the shoddy, unprofessional work done to rebuild the dam, the courts never held the club or its members accountable. The courts, mostly in Pittsburgh where club members held sway, accepted that it was an act of God. It’s clear to more objective observers that a properly built dam would probably have survived the flood, or at the very least would have had a much less damaging failure. Though McCullough suggests the residents of Johnstown and the members of the club were too trusting, he does not shy away from the negligence of those who rebuilt the dam in a way that would almost surely lead to the disaster that came.
