you a window into the life of the sender, and sometimes into the life of the receiver. But they often leave mysteries in their wake, and this letter is no exception. It was written in the fall of 1843 by Hatfield native Dr. Waitstill Hastings from Erie County, Ohio. He’d married Lucinda Wood in Herkimer County (NY) around 1796, and thereafter they raised eight sons in Ohio. He wrote this letter to his “dear Sister” Mary (Hastings) Wait – the widow of Daniel Wait, who’d died 10 years earlier.

It wasn’t easy being a physician in the 19th century, and this letter suggests a few reasons why. Dr. Hastings was late in writing to his sister because he was chasing a fugitive who’d skipped town in the middle ofsensors replace the point sensors of the first method and determine the projectile's location based on the arrival times of the metal borne shock waves at transducers on the ends of the rod sensors. Only the speed of sound in the metal rods and the time of arrival of the metal borne shock waves at the transducers are needed to determine the "hit" coordinates. As is the case for the point sensor system above, the flight path of the projectile must be substantially perpendicular to the target plane for the "hit" to be determined accurately by the rod sensors.
Since this new invention relates to the improvement of the scoring apparatus which uses rod sensors to score "off-axis" (non perpendicular) projectile flight paths with respect to the target scoring
