We have on hand at the nurseiy and at Makiki Station a large variety 

 of forest and ornamental trees ready for planting out. We are also 

 propagating for the coming planting season quantities of forest and 

 ornamental trees of many species. 



COLLECTION OF SEED. 



The seed season is now on and the seed boys are busy collecting. 

 Our success in collecting koa seed has not been so great as we would 

 have liked, nevertheless we have managed to get some good seed. 



We have received from Mr. P. J. Wesster, Agricultural Advisor, 

 Zamboanga, P. I., seeds of Drcwaena sps., Gymira mvemontosa and Parkia 

 timonana, which we hope will prove to be valuable as well as ornamental. 



MAKIia STATION. 



Our efforts at this station are directed toward the propagating of 

 large quantities of trees to be ready for the rainy season. We intend 

 to have ready enough trees and plants to meet all demands.
