it was stated that external examination of NiTarcissus bulbs cannot
be relied upon to determine their freedom from infestation by the
bulb eelworm, Anguillulina aipsaci. In order to prevent the dis-
tribution within the United States of foreign Narcissus bulbs in-
fested with the bulb eelworm and at the samc: time to provide for
unlimited entry as to number and vcriety, it wvas further announced
that under the provisions of regulation 9 of Nursery Stock, Plant,

degrees F., preferably 75 degrees, for a period of two hours after
which the bulbs are to be held in hot water until all the bulbs
have reached a temperature of 110 to 111 degrees F., throughout.
The bulbs are then to be held in hot water at a tcmpcraturu of not
less than 110 decrees F., for r. pr-riod of four hours. As a pre-
cautionary measure to chock the subsequent dissemination of dis-
enses such as basal rot, a pint of formr.lin nr.y bi added for each
35 gallons of water, but the addition of the disinfoctknt is op-
tional with thu importer.
