The position that was not one of the four positions in predisent Washington's Cabinet was Secretary of interior.
Explanation:
The secretary of the interior role is not very new, but it wasn't present in president Washington's Cabinet because of the countries infrastructure and development. To understand this we need to know something. The Secretary of Interior is in charge of the conservation of federal land, and natural resources. In the days of President Washington, the low stage of development of the country didn't make this role possible. Also, the first one was appointed in 1850 so is nothing new. But again, because of the objectives at the time, the role didn't exist, there was not enough vision.
