In October 1963 the peal bells were installed in the central tower of the cathedral by Harry Parkes from the Whitechapel Foundry in England.  Not until they were installed, however, did it become apparent that no one knew how to ring such bells. After the installation Parkes extended his stay in order to train a group of  adults at the cathedral and students from St. Albans School.  A book was provided but more instruction was essential.  In May 1964, a group of ten ringers from England came to Washington to ring the dedication peal and give instruction to the local ringers.
