Discussion after Mr. Slate's paper—
MacDaniels: "Of the 1999 seedlings tested at Geneva, 52 are being carried on for further observations. Prof. Slate is doing a fine work."
J. R. Smith: "I want to express my appreciation of the work Prof. Slate is doing. To care for 1999 seedlings and keep the performance records is a big job and just the kind of thing on which progress depends."
