"Constant Reader," Hoosick Falls, N. Y., writes: "I am very much troubled of late with the above mentioned attacking the leaves of my American Beauties and taking the vitality right out of them - thereby rendering the blooms very unsatisfactory. And I perceive it is spreading to some Bennetts planted close by. It is to me a new enemy in the cultivation of roses. Would like to hear from some of the readers of your valuable paper on the subject - more especially Peter Henderson or some of the noted rose growers".

[This matter was very ably discussed by a number of the noted rose growers of America at the florists' convention last summer. Every one of them had positive opinions of his own, but according to our observation, no one succeeded in convincing the others that they were wrong in their views. The only facts on which there seems to be no disagreement are, that the trouble comes from the work of a minute parasite fungus; and that this fungus is a new-comer among rose growers.

The drift of the discussion indicated that most of the noted growers believed bad treatment started the fungus on its work. Rain water, hard water, cold currents, too low temperature, too much forcing causing lack of vital power to resist attack, bad soil, and many other things, that might bring about this growth, were offered as guesses, but nothing more.

It may be conceded, we think, that fungus parasites do not readily grow on vegetation unless vegetative power is not at its best, - hence the protection must be sought for in obeying those laws of plant-life in our treatment that tend to healthy vegetation. Fungus, however, may be destroyed. It is known that oil, sulphur and salt are all enemies of fungus growth, and, if one is chemist enough to know how to help an atmosphere in its oxygenic particulars, some good might be obtained from this great enemy of fungus also.

Now all these are ascertained facts, and it only remains for some genius to put them into such shape for practical use, that he who runs may read, as the Scriptures say___Ed. G. M].
