Abstract: An apparatus for providing test containers to a test position, includes a track adapted to guide test containers to a test position, a magazine adapted for holding a plurality of test containers and operatively engaged with the track to provide test containers to the track, and a drive mechanism adapted for moving individual test containers from the magazine and along the track to the test position. The magazine for serially providing a plurality of test containers, includes a housing forming a chamber adapted for holding a multiplicity of elongated test containers in parallel and adjacent alignment along a row, a stop element formed at one end of the housing in parallel alignment with the test containers, and a biasing mechanism adapted for physically biasing the row of test containers against the stop element, wherein the one end of the housing including an opening located adjacent to the stop element and adapted to allow test containers to be removed from the chamber.

Abstract: A watering arbor apparatus includes a fan-like arrangement of hollow tubes converging to a common junction at lowermost terminal ends of each tube defining an elongate tubular reservoir, wherein the reservoir is in fluid communication with a lowermost hollow conical end, wherein the conical end includes a matrix of apertures therethrough to effect watering within a ground support of the apparatus. Modifications of the instant invention include extension members to extend the capacity and height of the organization, as well as selectively securable caps to restrict flow during periods of saturation in use of the apparatus. Further, an electrical heater is mounted within the reservoir for optional heating of the reservoir during frost like conditions to provide additional heat to a root system of an associated plant.
