grounds in Kahului, on October 13 to 15, 1921, by a display 

 representing- the activities of each of its four divisions. 



The Division of Forestry had the largest exhibit which con- 

 sisted oi a fine assortment of more than fifty species of trees, 

 raised by Ranger James Lindsay at the Board's nursery in 

 Haiku, and arranged tastefully on a large pyramidal table; the 

 working rainfall-erosion model which once again demonstrated 

 most forcibly and practically the beneficial controlling influence 

 of a forest cover upon the runoff; and a diagrammatic poster 

 explaining just how trees grow. Among the innovations this 

 year were a very complete collection of tree seeds arranged in 

 vials by the Forest Nurseryman, a set of thirty photographic 

 enlargements with explanatory captions illustrative of forest 

 work in Hawaii, a collection of plain and polished boards of 

 the more important native and introduced woods cut from trees 

 grown in Hawaii, and a novel collection of fresh boughs of 

 pines, spruce, and cedar brought down from trees now growing 

 in the experimental plot at 7,000 feet elevation on the slopes of 

 Haleakala. 



Small sample blocks of the real sandalwood, a variety of 

 seeds, and farmers' bulletins and agricultural year books were 

 given out from the exhibit stand. 



The Division of Entomology was represented by a collection 

 of cases of the insect pests of the Territory with specimens of 

 the beneficial insects which have been introduced to prey upon 

 them. Some of the latter were also exhibited in living form. 



The Division of Plant Inspection display included insect and 

 pathological specimens from other countries taken during the 

 inspection of imported fruit and plant material and, as well, 

 specimens and descriptions of some of the serious pests which 

 have never appeared here and which this division seeks to keep 

 out by rules and regulations and by the careful inspection of all 

 importations which may harbor them. 



The Division of Animal Industry exhibited charts showing 

 progress in the control and suppression of infectious and con- 

 tagious animal diseases in the Territory and pathological speci- 

 mens representing lesions developed by bovine tuberculosis. 



The displays were more extensive than at previous fairs, 

 were highly attractive to the visiting crowds and produced very 

 favorable comment. A special prize of a pink ribbon was award- 

 ed to the exhibit as a whole. 



Lessons learned from this fair show the necessity of prepar- 

 ing beforehand a ground floor plan of table and stand arrange- 

 ments and of carefully labelling all ^exhibits so that the ortho- 

 graphy will be correct and the labels legible.
