It was wise of him to do that because they can conserve the trees and during the sandalwood trade the worker spent too much time with the sandalwood so, the workers could spend more time cultivating their fields (page 26). This is something that changed because, before the unification of Hawaii there was no such thing as the sandalwood trade. This was very good because now they won't run out of sandalwood trees quickly and more of the worker will spend time cultivating their fields.
Kamehameha was an effective leader because he was very helpful to his people. One reason why Kamehameha was an effective leader is because he charged visiting ships for harbor, pilot, and port fees. (page 28)It was helpful for him and his people because now he can gain more things from foreign people and places also Kamehameha’s people can get more things. This is something that changed because before the unification of Hawaii they did not charge people for harbor, pilot, and port. This was very good because now they can get more things and Kamehameha can earn a profit.
