Work on the long-awaited project to return the original Pettingill School cornerstone to Pettingill School Park began Friday, Oct. 5. Mark Labonte Landscaping donated their services by digging a four-foot pit in preparation for the groundwork. The students of Lewiston Regional Technical Center under the supervision of Tom Fylstra and Alan Merritt will commence work on installing the cement framework, laying the cement and building the brick base to support this historic artifact. The cornerstone has been in storage for the last few years until the Friends of Pettingill was able to raise sufficient funds to complete the project.
