even under seemingly favorable conditions. The shrubby and arbor¬ 
escent Pomece and Prunece , especially the stone fruits, are the principal 
sources of infection. If we could control the disease in our orchards, 
the danger from outside sources would be slight. 
The question of treatment naturally divides into two portions (a) 
orchard hygiene and (b) use of fungicides. 
From what has been said it is apparent that two factors are neces¬ 
sary to the production of the rot: 
(1) The presence of the rot fungus ; 
(2) The existence of meteorological conditions favorable to its rapid 
development. 
The control of meteorological phenomena being impossible, the ques¬ 
tion arises: Can the rot be held in check by the destruction of the 
fungus? Fortunately we are able to give an affirmative answer. In 
this connection the importance of knowing where the fungus passes the 
winter becomes strikingly apparent. If its preservation through the 
winter and its reproduction in the spring depend wholly or in great 
part upon the existence of a dormant mycelium, then the systematic 
gathering and burying or burning of all rotten fruits iu summer and 
autumn will very materially lessen the prevalence of the rot. Especially 
will this be true if the work of destruction is continued year after year 
as all work of this kind must be. The remedy here proposed rests on 
sound principles and is both practicable and practical. If applied on 
a large scale, systematically, throughout a peach district, and for a 
series of years, it could not fail to bring decided results. To be very 
successful it must be done thoroughly and by united effort. Too much 
stress can not be laid upon the removal and destruction of all the rot¬ 
ted fruits. None must be left upon the ground or upon the trees. More¬ 
over, all the fruit-growers of a locality must unite if they would get 
the best results from this method, which is precisely that recommended 
for the extermination of noxious weeds, i. e., allow none to go to seed. 
Every husbandman knows that, in spite of thrift and painstaking, 
the farms ot a whole community are threatened if only one man allows 
his fields to become the nursery of bad weeds. From the fields of this 
careless or negligent person the seeds of pestiferous plants are carried 
by animals, washed by rains, blown by winds, or transported by the 
hand of man outward in all directions, to curse the industrious. In the 
same way in dealing with this fungus one neglected orchard may fur¬ 
nish spores enough to reinfect all the surrounding orchards. In union 
only is there anything like safety. On the start it will be hopeless to 
expect united effort but this will come in time. Men who will not prac¬ 
tice well-established rules of orchard hygiene ought to abandon fruit¬ 
growing. They are behind the times and in the wrong calling. Suc¬ 
cessful fruit-growing requires men of brains and decision. Prices are 
low, competition is severe, and, if any money is to be made, this busi¬ 
ness must be conducted intelligently in the light of all the knowledge
