Mr. Henderson kindly sends us another wail, from " Dr. W. H. H.," Frankfort, Ky.,and remarks: "Here is another victim. If you wish to benefit your species, put up on every issue - Gas Tar!! Beware ! ! - and even then though they would tumble in".

But the fact is, this gentleman's name is not on our subscription books. We insert, however, the letter as a suggestion to our friends that if they have any neighbors who love gardening, but do not subscribe to the Gardeners' Monthly, it might save them no end of vexation and cash, to take the magazine. But here is the letter:

"Please tell me why many plants in my conservatory look as if the leaves had been browned by a hot sunshine. Even my young thrifty geraniums have suffered severely. A large Niel in the end of the house, putting out hundreds of young thrifty shoots and leaves, has dropped every young leaf. My conservatory is heated by a No. 4 Hitchings Conical boiler and the temperature is very uniform, from 500 at night to 650 or 700 during the day. I am at a total loss to account for it. Can it be from the pipes ? Now, the pipes the plumber used are 4-inch pipes and are coated with some black substance that gives"out a strong smell of coal tar, when the water gets very hot. Several times in the morning I have noticed this so strong as to be very unpleasant, and look as if there was smoke in the house. Do you think it can be this gas that is doing the mischief ? I noticed this state of things after two particularly cold nights, when the firing had to be increased and the water in the pipes got so hot as to melt the coating on the pipes.

I would be glad to have your opinion on this, for it troubles me very much".
