Abstract
A periscope of the present invention is adapted to allow a farmer to monitor the inside of a wagon while it is being filled with grain from a grain cart. In this way, the farmer will know when the wagon is full and can prevent the wagon from overfilling and spilling grain. The top mirror of the periscope is convex in shape and can be adjusted to change the field of view.
