The clipping is part of an advertisement for Lord and Burnham Greenhouses, published in the Florists' Review, October 26, 1916. Note that the headline incorrectly places Hatley Park in Vancouver, B.C., and incorrectly titles James Dunsmuir as a Lord.
The greenhouse and conservatory were constructed and installed by the Lord and Burnham Company and they later used the estate installation in their promotional material. The glass house complex had a full time manager and required 60 tons of coal and 200 cords of wood per year to heat. The ornate conservatory had a central dome of about 30 ft square, with two side galleries, each 60 ft long. Flowers were grown inside that were intended for display in the castle and in later years it was also used for food production. According to a former gardener, interviewed in the 1950s, Laura Dunsmuir said that the conservatory was an extravagance in a private garden and that it should be in a public park.
