A pastor's wife was expecting...

A pastor's wife was expecting a baby, so he stood before the congregation and asked for a raise. After much discussion, they passed a rule that whenever the pastor's family expanded, so would his paycheck.
After 6 children, this started to get expensive and the congregation decided to hold another meeting to discuss the pastor's expanding salary.
A great deal of yelling and inner bickering ensued, as to how much the pastor's additional children were costing the church, and how much more it could potentially cost.
After listening to them for about an hour, the pastor rose from his chair and spoke, "Children are a gift from God, and we will take as many gifts as He gives us."
Silence fell over the congregation. In the back pew, a little old lady struggled to stand, and finally said in her frail voice,
"Rain is also a gift from God, but when we get too much of it, we wear rubbers."
The entire said, "Amen."

Steam percussion rock drill

In 1849, Joseph J. Couch received the first U.S. patent for a steam-powered percussion rock drill (No. 6,237) as “improved machinery for drilling rocks”. It was driven by steam power and acted without need of gravity supplying any part of the motion. A sliding drill support frame enabled it to be operated in any desirable position or direction. Power was supplied by the piston of a steam cylinder connected to a suitable steam generator. The machine would be held stationary as the rotating drill was thrown against the rock. The drill rod would disengaged at each stroke, and travel with its own momentum, so that upon striking the rock, the shock was not transmitted back to the rest of the machine, preventing it from damage. After each blow, the tool was seized by means of friction-grips to retract and repeat.«
