My trees suffered so much from apple scab in 1882 or 1883 that they did not recover sufficiently to fruit till 1886. It is possible that checking growth may develop fruit buds, but loss of foliage we have always found to be a calamity here, where our severe winters often emphasize the effects of any weakness a tree may possess at the end of the growing season.

I once entertained the idea that wet, cold weather induced the scab, but further observations and experience has led me to conclude that it is in humid, hot weather when the scab runs riot. We had plenty of scab this season, and this winter may kill many of our trees.

After two years experience on twenty-five acres of apple orchard, I have concluded to abandon the use of London purple on account of its injury to the foliage. I suppose I shall use Paris green for an insecticide; and for a fungicide we have tried nothing yet superior to the ammoniacal solution of carbonate of copper, but have hopes of something better to experiment with next season. The ammonia is a solvent of arsenic, and will, therefore, not make a good compound to act as both insecticide and fungicide when used with Paris green. - A. L. Hatch, Ithaca, Wis.
