"In the period from 1824 to 1833, the tendency was steadily in the former direction, but it was only in the latter part of it that it was made really efficient"

Henry Charles Carey's quote is referring to a period of time in which a certain tendency was progressively increasing in effectiveness. From 1824 to 1833, this propensity was gradually becoming more effective, however it was only in the latter part of this period that it was truly efficient. This suggests that the tendency was not instantly effective, but rather took a while to reach its full capacity. This might be analyzed as a metaphor for any process that requires time and effort to reach its preferred outcome. It is a pointer that perseverance and dedication are necessary for success, which it is just through perseverance that a person can accomplish their objectives.
