30 Inaugural Address by the President. 



knife F^ so as to distribute its strokes over the whole of the 

 meat. This rotation is effected by the inclined grooves G^ in 

 the collar break which engage with catches on the heads of the 

 contact springs causing a turning movement each time the 

 collar is drawn upwards. 



A quick reciprocating motion of the kind we have here 

 might be applied to many things such as hammering, rock 

 drilling, etc. I have, as an experiment, fitted a hammer to this 

 apparatus which can be controlled like a steam hammer. 

 Again by turning the whole thing upside down and attaching 

 to the cone a fret-saw or jig-saw with a spring take up, it has 

 been made to saw also. 



By substituting another core with a suitable plunger it is 

 converted into an egg beater of great convenience and efficiency. 

 The addition to this of an adjustable oil dropping arrangement 

 gives it the power of making an excellent mayonnaise. 

 Mayonnaise making, according to a high authority, requires 

 " time, patience, and nicety." When these matters are 

 arranged for in the machine one simply puts in the egg, oil, 

 vinegar, and condiments, switches on the current, and in 

 twenty or thirty minutes there is an excellent mayonnaise. 



I now pass on to what is perhaps the most important electric 

 invention of the last few years, namely, wireless telegraphy. 

 In ordinary telegraphy the message is transmitted by means of 

 electric currents in an insulated wire from the sender to the 

 receiver, returning by the earth through earth plates, connected 

 one to each end of the wire and buried in damp soil or in water. 

 In returning through the earth the current does not confine 

 itself to one path but spreads out through the earth. If we 

 insert in the path of a portion of this earth current a second 

 pair of earth plates and wire, we shall get a part of the earth 

 returned current in a wire connecting these plates sufficient to 

 affect a telephone, so that signals made by the current, in the 

 first mentioned wire, can be heard in the telephone. Such a 

 system is, I understand, in successful operation between Rathlin 

 Island and the mainland at Ballycastle.
