This course will not, however, suit every case, for when the rot has spread in many directions, the best and cheapest course is to consult some professional man, well versed in the peculiarities of dry rot, before determining upon any remedy, for we have shown in the course of this work that the disease may arise from various causes; and it is not a difficult matter to select the wrong remedy, and thus increase the disease.
We trust the reader has found in this volume at least some hints which may be of service to him. A _new_ house affected with dry rot is an unhealthy one to live in, and an _old_ one is worse than the new; we mean the kind of house referred to in one line by an American poet, as follows:
“O’er whose unsteady floor, that sways and bends.”
