. Canadian forestry journal. Forests and forestry -- Canada Periodicals. Canadian Forestry Journal, June, 191S 1745 tinned in Eastern Canada. This is a serious blow at what has been a prime and perfectly sound principle in the practice and plans of forestry in America. The first and most valuable choice of trees for reforestation pur- poses is removed from the list. At all events, to plant white pine in Eastern Canada is almost certain to bring loss 'And disappointment and with that a lowering of the planting enthusiasm. If we can keep the disease out of northern Ontario and Quebec, white pine could be safety planted there only if it were obtained from stock grown in the North or West. 5. Whether or not white pine plantations, of which there are several in Canada, should be annually in- spected or eradicated, should be de- termined entirely by the circum- stances of the case. Where eradica- tions are effected it would seem desirable that the government should replant with other species of trees. 6. There is no evidence yet, so far as I know, that the blister rust has been carried to America in European currant or gooseberry stocks. Yet there is a possibility that it could be, and as long as that uncertainty pre- vails, these stocks should l)e placed under the same embargo conditions as the pine. Guarding the West 7. There is absolutely no question in my mind but that the various cultivated varieties of Ribes, and especially black and red currants, are the most potent agencies in the spread of the blister rust. There is a free and extensive movement of these commodities throughout Ontario and the other eastern provinces, and the disease is very readily spread from these plants to others of their ow^n kind as well as to the pine. It is equally certain that the disease can be spread to the West in the same way This opens up one of the difficult features in the situation, the only solution of w^hich lies in an embargo for the present on the shipment of currants and goos
