The trumpet ; is intended to be need for bis discovery of the great distance an echoed or retetberaied sound will carry, and the discovery that speaking , trumpets, if made to give the same fundamental ftote, would vibrate and produce the phenomenon known as “ sympathy,” this trumpet conversation in an Ordinary tons of voice was carried on between partial four and a quarter miles apart, PeopW sitting at their windows Ojr fln their., pitches a mile away, conversing man ordinary tone, could be distinctly hesrd, and in two instances they were told the nature of their con. Tcretiion and admitted that such had ta|(sp place, By listening to the whistle and tracing it to and beyond Fernbank Lawrenceburg, Indiana, it was fonnd tliffrthe instrument bad a well-defined (range 0M26 miles ; that is, A loud sound ]s)ce.a locomotive whistle or the rumbling pi a train could be distinctly heard at the distance hi 13 miles in every direo-

ion. Conversation was readily carried on between men on bills on opposite sides of the Ohio river, about four and a half miles apart. Tests made on the water showed that the trumpet was even more available than on land. The instrument will be patented as soon os perfected, A name has not been chosen for if.
