Cyclopedia of American horticulture, comprising suggestions for cultivation of horticultural plants, descriptions of the species of fruits, vegetables, flowers, and ornamental plants sold in the United States and Canada, together with geographical and biographical sketches. Gardening. IRRIGATION IRRIGATION 835 joints. The first tile where the water is introduced is laid at an angle, one end resting on the edge of the bench side. This leaves a wide opening at the first joint, which is closed with cement. A better plan is to use a curved sewer-pipe for the inlet, but this is not always available. The picture (Pig. 1182) shows how the tile is laid on the bench bottom, being a view of a side bench in a carnation house. Following Goff's suggestion in the use of brick, tiles. 1183. Sub-irrigation with two tiers of tile. have been used over the entire bench bottom with good results, and it seems probable that this will be found to be the best form of construction, as it appears more certainly to insure an even distribution of water. The method of construction is the same as above de- scribed, for the two plans differ only in the number of tiles employed to distribute the water. When the bench bottom is covered with tile, placed near enough together so that the soil will not fall between, it will be readily seen that water introduced at any point will flow to all parts of the bed in and around the tile. It needs simply to be brought up to such a level that it will reach the soil, when capillary attraction will complete the dis- tribution. Fig. 1183 shows a bench in a tomato house constructed after this plan. AA are the inlets; B the irrigating tile, from which the soil has been removed; C is the tile bench bottom, covered with cement. The same size of tile, viz., 2K- or 3-inch, is used both above and below. D is the cement side, which has been broken away to show the method of construction. The outer board has been removed also. The cost of construction need not be discus
