portance of these predatory insects was em])hasize(l because it is 

 their predaceons activities which make tropical agriculture pos- 

 sible by preventing the increase, to epidemic numbers, of serious 

 insect pests. Se\eral collections of miscellaneous insects served 

 to fascinate the curious with their contents of giant grass-hoppers, 

 weird "walking sticks," and huge rhinoceros beetles. Many a 

 shuddering gazer at these ugly creatures learned for the first time 

 that it is Only by constant vigilance on the part of the Territorial 

 inspectors that such pests are kept out of the Hawaiian Islands. 

 The Division of Forestry in its exhibit also emphasized the 

 educational features. One-half of its allotted space was occupied 

 by a large table, 8 by 16 feet in size, covered with growing trees. 

 The table was built up pyramid-fashion by steps and on these 

 were placed flats of young seedlings and small trees in green- 

 painted pots, making altogether a cool refreshing spot in the 

 general heat and hubub of the Fair. Nearly every species of the 

 trees used in reforestation work was represented, but there were 

 also many ornamental and shade trees such as the showers, 

 monkeypods, false kamani, various palms, banyans and others. 

 One side of the table displayed several choice varieties of Euca- 

 lyptus in seedling flats and pots. From the center of the table 

 rose a signboard in the shape of a Japanese torii with posters 

 explaining on one side the processes of growth in a tree, and on 

 the other carrying the following announcement : 



THESE TREES 



Were raised at the Haiku Nursery at Haiku, Maui. 

 This nursery is now operated by the Board of Agri- 

 culture and Forestry for the benefit of the people of 

 Maui and Molokai. Forest Ranger James Lindsay is 

 in charge and will furnish any quantity of trees for 

 forest or ornamental planting, at cost. Next month, 

 on Arbor Day, trees will be given free to all who want 

 them. Get busy and plant a tree ; plant hundreds of 

 them ! They grow while you sleep and your chil- 

 dren's children will bless your name. 



Opposite the tree table there was constructed an "erosion 

 model" such as has been shown several times in Honolulu but 

 which had never before been exhibited on Maui. This miniature 

 illustration of the disastrous effects of deforestation proved of 

 absorbing interest to many adults as well as to the hundreds of 

 school children who paused to study it on Friday, which was set 

 apart as children's day. The model was six feet square, and was 

 buih to slope gently forward at a convenient height. The left 

 half of the box showed a tree-clad mossy mountain drenched by 

 a steady spray of water which trickled by little rivulets from the 

 base of the mountain, formed a minature winding river, and 

 ultimately found its way into a small clear lake. On the right a 

 barren mountain of red earth, although "rained" upon by a spray
