Transactions of the New Hampshire state Agricultural Society, for the Year, 1860 … Pp. 189 Herod Chase of Deering, NH submitted his farm for an agricultural contest and took "1st Premium." Of interest is his statement "The farm is well walled and bushes kept down. When I moved on the farm every acre of the field was covered with stone-heaps, from 25 to 40 per acre, and now not one is found in the mowing." It would interesting to determine if he was the first land owner of this parcel, and if so, it would be eyewitness account of cairns existing prior to agriculture use of the property.
