overtask

But a strong desire to improve and elevate the schools, led him to overtask himself.

The work is too severe for African thews, and experience has shown it a bad economy to overtask the slave.

Not to reveal too much, and not to tire curiosity or overtask belief, was his daily labour.

But it is lost if we overtask the perceptions and carry away no idea with us: there is no gain, and positive harm.
