down in the soil.

The protection device against rot of wood in the earth, applicable for wood Columns, bars, etc., are shown in the drawing.

α is an internally ribbed tube, closed at the bottom, provided with a strong bevel at the top, to which a raised part b is attached; the rod c is placed in this tube. At some distance above the opening of this tube an incision is made around the pole, in order to put up a screen d to prevent the rain from entering the tube. This screen can be made of sheet metal and nailed on, or made of oil-soaked canvas or roofing felt, and the latter can be tied up with wire.

The elevation b serves to prevent the wind from driving the rainwater into the pipe. The screen towers above this elevation.

A ring e of band iron, which is cast in the gate or which can also be attached outside, protects the tubes from shattering when using larger columns etc.

The tubes are usually ι m high, depending on requirements, of which about 3 feet into the ground come to a standstill; the remaining part protrudes.

Green poles can be split or sawn in crosswise and the cuts through wedges be kept open so that they dry out well. The wood then retains its toughness and suffocates not and makes no entry to the strength. By using this tube with a shield The aim is to keep the poles in the ground from any wetness and moisture from below and are protected at the top, as wind and temperature changes cause constant air admission into the the lower part is permitted by the ribbed trains and the wood always remains dry.

Any preparation, impregnation, firing, tar painting, etc., becomes superfluous.

Rods of unequal dimensions can also be used because they are thinner in some sand, which is passed through the trains, or in some mortar, which is previously in the Tube is brought, can be set. This gives thinner bars their strength below and above these are fastened with wedges, which are wedged into the ribbed cables will. This prevents any shifting back and forth.
