Above: Carrick was also responsible for the on-site installation work for the Scottish American War Memorial in Princes Street Gardens, Edinburgh. The sculpture and frieze were executed by the famous Canadian Sculptor and medical pioneer Robert Tair MacKenzie. Anne Scott remembered that MacKenzie visited the Carrick's while in Edinburgh and Carrick spent an hour with him in his studio where the two men modelled clay figures. MacKenzie was a pioneer in physiotherapy and athletics and became a sculptor through his interest in anatomy and movement in the human body. Carrick's career with Edinburgh Harriers might have been of interest.
Top: Following MacKenzie's death in the 1930's he was buried in Canada but, in accordance with his will, his heart was removed and placed in a casket set into the eastern external wall of St. Cuthbert's Church in Princes Stret Gardens were it would face the Scottish American Memorial. MacKenzie's family approached Carrick and asked what would be a suitable memorial for MacKenzie. It says a lot about Carrick that, instead of suggesting a grand monument, he offered the opinion that MacKenzie's true monument was his work, and that the casket should be marked by a simple plaque bearing the monogram RTM which MacKenzie used as his signature. Carrick carved the plaque from a piece of Doddington Stone left over from the Scottish American project.
