I am looking for a copy of the HDRA No-Digging report No 1 of 1969 by Lawrence D Hills that John Harrisons mentions in a paper he wrote on November 29th 2018. I cannot find it anywhere. Could you please tell me where I can obtain a copy as I am doing some research into no-dig techniques versus dig techniques. Thank you. Please email at the address below,
