THE HAWAIIAN FORESTER 

 AND AGRICULTURIST 



Vol. XIII. Honolulu, October, 1916. No. 10 



The time for tree planting, just previous to the rainy season, 

 approaches, and with it comes Arbor Day, which Governor 

 Pinkham has proclaimed shall come this year on November 17. 

 The origin of Arbor Day and its significance in Hawaii are 

 pointed out in the Superintendent of Forestry's article on the 

 subject in this issue and it is hoped that all tree lovers will cele- 

 brate the day by either planting a tree or caring for trees already 

 planted. "If a person does no other good in life than plant a 

 single tree, he confers a blessing on mankind." 



The work of protecting our remaining native forests from 

 damage by stock by the construction of suitable fences con- 

 tinues to progress and means a continued and greater supply of 

 water, the Hawaiian forests' chief product and the Hfe blood of 

 agricultural Hawaii. 



The second annual Hawaii County Fair held in Hilo on Sep- 

 tember 22 and 23 was a success in every way. The commodious 

 Kuhio wharf lent itself to the occasion and afforded plenty of 

 space for the exhibits and for the large crowds of people who 

 came to see them. The Board's exhibit showing the activity of 

 the four divisions attracted a good deal of attention and was vis- 

 ited by thousands of interested people. Probably the most no- 

 table feature of the fair was the splendid exhibit of pure-bred 

 pedigreed Hereford bulls bred and raised on the Parker Ranch. 

 These showed what can be accomplished in the livestock line in 

 these Islands by the right beginning and good management. 



The prompt discovery and extermination by Plant Inspector 

 Ehrhorn of a colony of Argentine ants which came from the 

 Coast with a shipment of plants on September 13, kept out from 

 Hawaii a bad pest which is becoming very bothersome in Cali- 

 fornia and the Southern States. 



The multiplication and distribution of parasites on the melon 

 fly and the corn leaf-hopper by Entomologist Fullaway are pro- 

 gressing without interruption, as shown by his .report for Sep- 

 tember.
