 Those several reductions confined it to a narrow strip, about long, from east to west, by two and three-fourths miles wide, from north to south.By an act of the legislature, approved April 10, 1849, its territory was still further reduced by the creation of the borough of Elkland, to which, from time to time, additions have been made.In January 1857, all that part of the township not embraced in Elkland borough limits, lying west of a line extending through the center of that borough, from north to south, was erected into the township of Osceola, and in December 1857, all lying east of the same line became the township of Nelson, and Elkland township passed out of existence.
