Taking into account not only the percentage of resin, but the aroma and general condition, Mr. Chapman considered in 1898 that the best samples were those grown on Plots X, S, C, A, and B. He placed them in this order, but observed that there was practically very little difference between these five samples. He placed the sample from Plot D next in value, and last those from E and F, which he considered to be inferior in value to the others.

The hop factors, who had the duplicate set of 1898 samples, placed B, C, D, and X together, as worth £7 2s. per cwt., placing A, E, F, and S in a somewhat lower class, but valuing them at £6 15s. to £6 18s. in the then current market.

In the case of the 1899 samples, the question of quality possessed, from the point of view of our experiments, even more interest than in 1898, since, from the yields of the plots, it was quite clear that some of the nitrate used must, in this season, have been superfluous as mere plant food, and the
