In designing the sets it has been borne in mind that they will not be operated by a skilled mechanic, but probably by a gardener or handy man. Everything, therefore, has been constructed with the object of making the whole plant simple and yet absolutely reliable.
Cheaper sets can be supplied if desired, but the results of a long experience prove that the set illustrated can be thoroughly recommended in every way.
