not to injure the roots of any sinnibs, trees, or roses. Root cutting 

 and root pruning will always dwarf any plant. In digging, it is not 

 wise to discard any leaves, twiggy growtlis, or weeds. Unless they are 

 required for the compost heap they should always he dug into the soil. 

 Leaf-mould is especially useful in any garden, and where such plants 

 as Azaleas, Rhododendrons, Liliums, &c., are grown, or for pot-plant 

 work, it is exceedingly valuable. In forming the compost heap, no 

 medium whatever should be added to help the rotting down of the 

 leaves unless it be a little sand. Any dhemical added will render the 

 mould un.suitable for its special objects. The plants mentioned above 

 strongly object to lime. 



All shrubs that produce flowers on tlieir young growths, including 

 roses, should now be pruned. Care should be taken to distinguish 

 between those "shrubs that flower on the new wood and those that flower 

 on the wood of the past season's growth. Those that flower on the 

 new wood, and may now be pruned, are Lasiandra, Lantana, Oestrum, 

 Tecoma, Hydrangea, Plumbago, Erythrina (some species), &c., and 

 those that should not be touched at ipresent time are Spirea, Erythrina 

 (some species), Pyrus Japonica, Weigelia, Prunus pissardi, P. Vesu- 

 vius, P. mume, Deutzia, Polygala, Ceanothus, &c. It is a safe rule in 

 pruning shnibs to wait until they have flowered before pruning. This 

 will certainly give the shrubs a somewihat ragged appearance in the 

 winter, but it is the only way to secure the best flowering results. 



All herbaceous plants, such as Salvia, Aster, Delphinium, Poly- 

 gonum, Boltonia, Gaura, and ChrysantOiemum, should be cut back, 

 and, if necessary, lifted and " heeled in " in a temporary location for 

 the winter. Plant out early Gladioli, Iris, and Liliums. 



Continue digging, manuring, and trenching. 



Vegetable Garden. 



Seedlings from boxes or seed plots may now be planted out. Care 

 should be taken that all vegetable beds are well raised and thrown up. 

 By throwing up the soil, and thus deepening the paths and the spaces 

 between the plots, the latter are well drained, and the soil is made 

 considerably warmer. This will greatly facilitate the growtih of the 

 3'oung plants. 



Asparagus may be planted; sow seeds of carrots, parsnips, cauli- 

 flowers, onions, peas, broad beans, and tomatoes, the latter being 

 forced on in a frame, so as to obtain good plants quickly.

HIGH COST OF SPRAY MATERIAL VERSUS CONTROL OF ORCHARD 



PESTS. 



The high cost of products in general has met with no exception 

 in the ease of materials used for insecticidal ,and fungicidal purposes. 

 While we have no proof that high prices of such materials have tended 

 to decrease the efhciency of spraying, there is every reason to believe 

 that such is the ease. Those who are most familiar with spraying 

 practices know that there is often too much of a disposition on the part 

 of the orchardist to economize in material and, as a result, his efforts
