A boiler with horizontal sections is shown in fig.
It has the horizontal racking motion mentioned FIG.
He showed that if an antenna were constructed with a short part of its length vertical and the greater part horizontal, the lower end of the vertical part being earthed, and if oscillations were created in it, electric waves were sent out most powerfully in the plane of the antenna and in the direction opposite to that in which the free end pointed.
The former bears a general resemblance to the Cherub log, but the dial plate is horizontal and the faces turn upwards.
In the second class there are, in addition to the lifting motion, two horizontal movements at right angles to one another.
