Abstract: A result is proved relating the growth of a subharmonic function $ u(z)$ of finite lower order at least one, along a ray, to the quantity

$\displaystyle B(r) = \sup \{ u(z):\vert z\vert < r\} .$

This sharpens a previous result of the second author when the lower order is finite. An example is constructed to show that the result obtained is best possible.
