By way of summary, it may be pointed out that the dweller on the farm now has at his command all of the household conveniences of the city dweller, and morever he can be fortified in the same degree, or even to a greater degree, against a contaminated water supply or offensive and insanitary final disposal of sewage, and this without excessive cost. It is impossible in speaking of sanitation on the farm, especially as it relates to water supply and disposal of sewage, to lay down hard and fast rules which may be followed blindly. On the contrary, it will be necessary in arranging for any of the conveniences outlined in the foregoing to take full cognizance of the influence of local factors. The problems presented are not, however, difficult or at all complex, and with a moderate amount of study the up-to-date and intelligent farmer can with but moderate assistance from the agricultural engineer design and install water supplies, sewerage systems, plumbing systems, heating and ventilating systems, and all that is necessary of a material nature to render the comfort of life on the farm complete and its appointments even luxurious.
