Infectious abortion in cattle has unfortunately made its appear- 

 ance on Oahu. Every effort is being made to control it Joy the 

 use of an effective vaccine, a supply of which was secured at 

 once upon the discover}^ of the disease here. 



The native wild begonia, akaakaazca, was found early in April 

 to be in full bloom in the shaded ravines at Kokee, Kauai, and on 

 the forest trail to Kalalau Valley. Its delicate pink and white 

 blossoms showing above the solid banks of ferns made a charm-

 blossoms of the poolammi, in the same region, also presented a 

 pleasing contrast to the usual abundance of green verdure.

 damage, but a close examination of almost every young mamani 

 tree will show that it has been severely cropped and consequentlv 

 stunted in growth by the repeated browsing of cattle.
