Abstract: The water reservoir for plants comprises a single sheet of flexible plastic material. Fasteners are employed to join the ends of the sheet together to form a continuous circle or collar. The sheet is positioned in a trench that is excavated to receive the new plant, thereby forming a barrier around the roots of the new plant. After the plant is placed in the excavated trench, dirt is used to fill the space outside the walls of the sheet. The space inside the walls of the sheet, containing the root ball, is filled with water.

Abstract: A pedal keyboard operated musical instrument includes a keyboard housing formed as a shallow, upwardly opening coffer. A spacer bar extends laterally in the housing, with a plurality of spring bars arrayed in parallel fashion and secured atop the spacer bar in generally orthogonal relationship thereto. The spacer bar bisects the longitudinal extent of the spring bars, which are unsupported at their opposed ends. A first and second plurality of pedal keys are secured to the spring bars, in alternating fashion, with each key of one plurality disposed between a pair of the keys of the other plurality. In addition, each key of one plurality is secured to one end of each spring bar, with a key of the other plurality secured to the other end of the respective spring bar. The keys of the one plurality are provided with blocks extending upwardly therefrom to extend above the nominal height of the second plurality, the blocks being adjustable in the longitudinal distance from the medial spacer bar.
