A system of Relief Stations of this kind must cover a given area completely in order to realise its purpose, which is to assist destitute wayfarers to travel in search of work without being under the necessity of begging. The best developed system yet in existence is weakened by gaps here and there, and it was with a view to perfecting the network of Stations in Prussia that the Government of that country, on the initiative of Pastor von Bodelschwingh, passed the law of June 29, 1907, for the establishment of Labour Depots for travelling work-people (_Wanderarbeitsstättengesetz_). This novel law gives power to the Diets of Provinces to require urban and rural districts (circles) to establish, maintain, and administer Labour Depots; such decisions must be supported by a majority of two-thirds of the votes given. It is the purpose of these Labour Depots to "procure work for destitute able-bodied men who are in search of employment away from their place of residence, and meantime to provide them with food and lodging in return for a task of labour." Districts in which Depots are not established may be required to contribute to the cost of Depots elsewhere by which they benefit. While the cost of the Depots falls, in the first instance, on the Districts, the Provinces must refund to them two-thirds of the costs, and the State contributes to the cost of all Labour Registries carried on in connection with Depots. Communes in which Depots are established must co-operate with the Districts in their management, and on payment must provide suitable buildings, so far as these have hitherto been used for the same purpose. A fully organised Labour Depot, as contemplated by this law, comprises, in addition to a workshop or workyard, a Hostel in which work-seekers are lodged and fed in return for a task of work, and a Labour Registry. It is not necessary that either Hostel or Registry should be carried on independently of existing institutions of the kind so long as these are efficient and it is possible to come to a satisfactory working arrangement with them. It is required that the work to be performed shall entail real exertion, yet be suited to every man's capacity, and as far as possible be in keeping with his normal occupation. As to the food supplied, it is stipulated that it shall be simple yet "so abundant that the wayfarer may remain capable of walking and working and may not be compelled to beg on the way." The admission of wayfarers to Labour Depots and their travelling from one Depot to another are to be regulated by rules issued by the Provincial Authorities.
