6. Spraying. Much information is to be found in Horticultural Journals and papers, and in Bulletins to be obtained from the Secretary of Agriculture for Ontario.
Illustrated articles on gardening and fruit growing should be collected for school use. Views of fine gardens, parks, and home grounds will be of interest to the pupils. Simple artistic methods of ornamental planting with trees, shrubs, vines, and herbaceous perennials can now be introduced, and some scheme for improving the school grounds outlined.
Catalogues should be obtained soon after New Year's and, after examining their merits, the best varieties of seed and fruit for the district should be selected. Horticultural societies, as well as Dominion and Provincial Departments of Agriculture, commonly give selected lists with descriptions of the different varieties.
