HiBERXACuLA 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 

 davs 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 -i, 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 

 spraving at the proper time, two sprayings were sufficient. 



Mr. Hambleton suggested that the members of the club do 

 more svstematic work on the birds of the state. 



The clul;) then adjourned to meet the first Monda}' in April.
