One of Mr. Burbank's hobbies, as the reader is aware, is "quantity production." Full explanation is given in the text of the reasons why Mr. Burbank finds it necessary to raise large numbers of individual plants in order to find material for his selective experiments. But such a picture as this shows that, when the conditions of soil are right, it is not always necessary to use a large space in order to produce a vast number of flowers. "Quantity production" by no means implies the use of a vast acreage. In point of fact, the famous garden at Santa Rosa contains only four acres, and the farm at Sebastopol only eighteen acres more.
