Tomorrow, Geo. W. WHITNEY and Miss WHITNEY, his daughter, who has received the appointment of teacher in china decoration in the Victoria Art School, Montreal will set out for the latter city. A native of this city, Mr. Whitney is one of its oldest business men. In 1836 he entered the establishment of John McMILLAN, the grandfather of the present head of J.& A. McMillan. To John McMillan suceeded David McMILLAN and upon his death, James and Alexander McMILLAN formed a partnership. On the death of Alexander McMillan, Mr. Whitney, who had all along remained with the house, became a partner. This was along in the fifties and Mr. Whitney remained a member of the firm from that time until 1888 or thereabouts, when he retired. He has been for 20 years a vestryman of Trinity Church and is a member of St. George's Society. He was for a number of years a member of Victoria division of Sons of Temperance. Some years ago Mr. Whitney met with a severe accident that left him permanently lame. He goed now to Montreal for the winter and perhaps permanently to avoid separation from his only daughter.
