the number is frequently all the designation that is needed so 
that the paper label may be dispensed with. One may if he cares 
to, mark all the slides he makes with serial numbers and his ini¬

referring to any slide irrespective of the paper label. 
Hibernacula of Utricularia.— Last fall (late Oct. or Nov.) 
I brought home several winter buds of Utricularia sp. and put 
them into my aquarium. They were'floating on the water all 
winter, repeatedly in ice, unchanged. With the first warm 
days and sun in March, they grew out rapidly and in a few days 
had developed branches several inches long, with numerous 
“utricles.” V. Sterki. 
MEETING OF THE BIOLOGICAL CLUB. 
Orton Hall, March 4, 1907. 
The meeting was called to order by the President. After the 
reading of the minutes Mr. Ball read a paper on “The Control 
of the Codling Moth.” He mentioned the difference of condi¬ 
tions between the East and the West, stating that the climate of 
Utah was such as to make the use of fungicides unnecessary. In 
his experiments he found that by using a driven spray, and 
spraying at the proper time, two sprayings were sufficient. 
Mr. Hambleton suggested that the members of the club do 
more systematic work on the birds of the state. 
The club then adjourned to meet the first Monday in April.
