the disease in Massachusetts. The black currant seems to be 
by far the most susceptible of any of the varieties to this dis- 
ease. ‘On learning of the outbreak at Geneva, we kept watch 
for this rust in Connecticut, and early in October received 
leaves of black currants from H. B. Birdsey of Meriden which 
showed the III stage of the fungus. These currants, originally 
obtained from outside the state, had-been planted in his garden 
about eight years, but he had not noticed this trouble before, 
though it may have escaped his attention. This year he noticed 
it because of the premature defoliation of the currants. 
After locating this rust at Meriden, we visited several nurs- 
eries, and inspected their currants to see if it occurred there. We 
also wrote to all the nurseries in the state handling black cur- 
rants, and requested them to look for the disease on the fallen 
leaves, as it was then late in the season; and to send us any 
suspicious ones. We were not able, however, to locate the rust 
in any of these nurseries. As black currants are not handled 
to any extent by our nurserymen, it is not likely that the dis- 
ease occurs with them. 
There are no white pines in the immediate vicinity of the 
rusted currants in Meriden, and Stewart has never found the 
peridial stage on the white pine at Geneva.. This makes it look 
as if the rust might carry over on the currants in some way 
without the aid of this stage for reinfection in the spring. In 
connection with Stewart and Stone, we have started, in the 
greenhouse, black currants that were last year badly infected, 
to see if the rust will again appear on them without the aid of 
the peridial stage. These plants were brought into the green- 
house in February, 1913, and at this writing, April 15th, although 
in full leaf, they had as yet shown no signs of the rust. From 
this it appears as if the fungus did not (at least commonly) 
carry over on the currants. Possibly we have not learned all 
about the life history of this fungus.

complaints were received of dampening-off in coniferous seed- 
beds. At the Station trouble of this kind was also noticed, 
especially among the white pines. A superficial examination
