the demonstration has been due to his constant emcienc}\ Acknowl- 

 edgments are due to Mr. George P. Thielen, James B. Castle, J. P. 

 Cooke, George X. Wilcox, and A. S. Wilcox, who came to the assist- 

 ance of the station at a very trying financial period, and contributed 

 $4,000 toward the cost of building a new tobacco barn, and for the 

 payment of other necessary expenses in connection with the experi- 

 ment. Early in 1906 the land commissioner of Hawaii, Hon. James 

 W. Pratt, reserved from entry for the use of the station, for the 

 purpose of this experiment, lot No. 17, Paauilo homesteads (PI. I, 

 figs. 1 and 2), this reservation to hold for three years if desired to 

 maintain a demonstration field during that period. The legislature, 

 in 1905, appropriated a sum equal to $228 per month for assistance. 

 A large part of this fund was used for the tobacco work. The re- 

 maining portion of the expenses of the experiment have been borne 

 from the regular funds of the station. 



Many experiments with the tobacco plant have been undertaken. 

 Seed has been planted every week in the year, and plants have been 

 set in the field in all seasons. Studies have been made of a number of 

 types of Cuban, Sumatra, and domestic tobaccos, and much valuable 

 data has been got together. The station has experimented on the 

 type or style of tobacco barn best suited to Hawaiian conditions. It 

 is believed that the one described on page 9 represents an improve- 

 ment in the curing barn over any type of structure used in other 

 tobacco countries. This preliminary work, if taken advantage of b} T 

 anyone entering upon the cultivation of tobacco on a commercial 

 scale in Hawaii, can be made to save a great deal of money. 



Demonstration experiments of the possibility of the introduction 

 of new crops are extremely expensive, and the funds of the station 

 will not admit of carrying on these experiments upon the former 

 scale. Some of the problems incidental to the successful growing 

 of tobacco may be continued, but the station turns over to the people 

 of Hawaii the results achieved and will leave to private enterprise 

 the establishment and further development of the tobacco crop. 



THE CURING BARN. 



The curing barn should be built before planting operations are 

 commenced. A group of buildings should be conveniently located, 

 and here in Hawaii, where the slope of the land is steep, they should 

 be erected at the lower edge of every 100 acres of planted land. 

 Curing barns containing 10,000 cubic yards of space will be neces- 

 sary for every 100 acres of tobacco, provided the structures are sup- 

 plied with artificial heat, as should be done. If no artificial heat 

 is provided, it will require buildings with from 18,000 to 20,000 

 cubic yards of space to care for 100 acres of crop. The buildings
