With the present almost universal employment of various fungicides for the destruction of blights, mildews and rusts on cultivated fruits and vegetables, we may confidently assert that the diseases of the filbert may be readily controlled by the same means. The spraying of the trees with Bordeaux mixture and other copper solutions will certainly destroy the fungus spores, and with these out of the way filbert culture may become of as much importance and as popular here as it is in certain countries of Europe. In my own experience I have found no other nut tree (barring always the blight) that has been more satisfactory. The plants come forward rapidly, fruiting freely and abundantly when young, and if properly trained, the crop can be gathered with little labor, and as it is ready for use a month or more in advance of the arrival of fresh nuts from abroad, the home market during the time is at our command. The number of applications of the fungicides that will be necessary during the season to rid the trees of blight, or the strength of the copper solution used, will depend somewhat upon circumstances and the condition of the subjects operated upon. If the trees are growing near hedges of wild hazels, where there is a constant or annual influx of the fungus spores, then greater care will be required to suppress them than if the trees are some distance from such sources of contagion; and it may be well for those contemplating planting filbert orchards, to examine their surroundings carefully in advance, in order to avoid local blight-breeding plants, and have these destroyed if any are found. I would also warn the cultivator against collecting branches of the wild hazel in the spring, carrying pollen-bearing catkins to be employed in fertilizing the pistillate flowers of the cultivated varieties, for by such means blight spores may be readily introduced into orchard and garden. It will seldom be necessary to practice artificial fertilization, where any considerable number of trees are grown near together, because if ninety per cent. of the male catkins are winterkilled, the few remaining will be sufficient to supply pollen for the pistillate flowers. In my grounds filberts have never failed to produce annual crops after reaching a bearing age, although they have been subjected to great extremes of temperature in winter. One year the trees were in full bloom the last week in February, and although cold weather followed, the protected pistillate flowers were not injured. The winters of 1894 and 1895 were among the severest, in the way of continuous low temperature, I have ever experienced here, and while the filberts did not bloom until the first week in April, the crop proved to be abundant.
