The present invention relates to a plug that can be fit into network ports. In addition to the foregoing, other method aspects are described in the claims, drawings, and text forming a part of the present disclosure. An upstanding transversely extending front stop mounted to the base at the front has an upper edge and at or adjacent the upper edge respective seats associated with the sets of at least two aligned slots. The cylindrical canister includes a sliding cover that is operable to open and close one compartment to allow stowage and release of the tree saplings. An annular wall having a greater inner diameter than the outer diameter of the pistons is formed on the inner wall of the cylinder body to support the back of each of the primary cups.
