The planet did not look promising, but they had no choice. When a / ship's drive blows between star-systems, it has to be fixed. If metal / parts must be recast and machined, and burned-out wiring has to be / pieced together and insulated by hand, the job takes literally months. / And if, then, getting home is a matter of more months of journeying / with a drive that still limps, while coughing and cutting off for / seconds or until it is tinkered with -- why, the traveler has to find / some way to renew his food supply.
It is for such occasions that the Interstellar Code requires all ships / to carry an emergency kit with seeds and agricultural directions.
