Maryland Laws 1833 Ch. 111 raised the reward for seizing runaways from six dollars to thirty dollars "whereas, from experience, it is ascertained the sum is insufficient to give that impetus to the apprehension of such runaways as the case really deserves and to remedy the evil thereof." But the reward was to be paid by the slave's owner, and slaveowners objected that the reward was too high for captures within the state. Thus, the law was repealed the following year "except so far as the same relates to slaves running away from another State, and taken up within the limits of this State, or slaves running away from this State and taken without the limits thereof."
