The Deanery (B. on plan) adjoins the Bishop’s House as above mentioned. It is by the same architect, is in the same style but of a more domestic type, forms a part of the same architectural composition, and is built of the same kind of stone. It is not so lofty a structure as the Bishop’s House, but has many interesting details, particularly on the southern façade. Its extreme outside measurements are about 79 by 93 feet. The late Dean Grosvenor occupied the Deanery from the time of its erection until his death December 9, 1916, and was succeeded by Dean Robbins in June, 1917. A tablet in the porch is inscribed: “The Deanery ‖ erected in ‖ Faithful Remembrance ‖ of ‖ Clinton Ogilvie ‖ 1838-1900 ‖ by his wife ‖ Helen Slade Ogilvie ‖ A. D. 1913.” [Illustration: THE BISHOP’S HOUSE] The Choir School The Choir School (C. on Plan) has a special interest for everyone who goes to the Cathedral, for here are educated and trained the boys who sing in the Cathedral services. The school was founded by Bishop H. C. Potter in 1901 and was formerly located in the Old Synod House. The present building, erected in 1912 and built of the same kind of stone as the Bishop’s House and Deanery, is in the English Collegiate Gothic style of architecture; is three stories high, and has extreme outside dimensions of 83 by 150 feet. Messrs. Walter Cook and Winthrop A. Welch were the architects. The building contains offices, a general school room which is equipped with apparatus for both stereopticon and moving pictures, a choir rehearsal room with stalls, individual rooms for vocal and instrumental practice, a fine large common room with open fire-place for reading and social intercourse, dining room, kitchen, dormitories, a big gymnasium, a sick room to which a boy is transferred upon the first sign of any illness, etc. Accommodations are provided for 40 resident scholars and 20 day scholars. Their musical training is under the personal direction of the organist and Master of the Choristers, and their general education under the direction of the Head Master and staff of under-masters. A sympathetic House Mother looks out for the personal wants of the boys and directs the domestic service; and competent physicians and trained nurses are in attendance when necessary. Boys are admitted to the school at the age of 9 and remain until their voices change, which is usually between the ages of 13 and 14. They come from all parts of the United States and possessions, two boys recently having come from Alaska. An applicant is first received on probation, and if he manifests a good character and disposition, and gives promise of a good voice, he is accepted as a chorister. Until they become full choristers, vested with cassock and cotta, probationers sit in separate choir stalls in the Cathedral services and wear only their black student gowns. During their residence at the school, the boys are under strict
