Theeleven plots laid out for the house inspected arefor the following crops : —1, Double White Nar-cissus : 2, Cos Lettuce, Cabbage, Cauliflower,and Carrots; 3, Tomatos and French Beans, thelatter to be gathered before the former are fully.

In this way the motion of the shaft be-tween the set screws takes up what little lostmotion there would otherwise be owing to tor-tion, so that the motion of the shaft is impartedto all the driving wheels instantaneously. Be-fore the actuating wheel has been moved roundone-sixth of its circumference the house is inmotion evenly at both ends, in spite of the factthat the gearing is 120 to 1. grown; 4—7, Asparagus in successive lots; 8,Mint; 9—10, Golden Spur Narcissus; 11, Or-natus Narcissus. The space covered by the elevenplots is one acre. When asked to name a rotationexcluding flowers, Mr. Pullen-Burry off-hand sug-gested three plots of Asparagus, one of Cauli-flowers, Cabbages, Lettuces, and Carrots growntogether, one of Turnips, one of French Beansand Tomatos together, and one of Globe Arti-chokes for a succession
