May June
On Thursday night, 20 June, the Chief Secretary in Adelaide receives a telegram from Charles Todd in Port Darwin the first message to be sent directly from north to south. But it has taken 29 days to arrive. First, it is telegraphed about 300 miles to the end of the Northern Sectionn of the OTL where it is written out and handed to Dick Knuckey. Knuckey then has to find his own way, on horseback, through rough country to Tennant Creek, the northern-most point of the Southern Section. Now the message can again be telegraphed down the Line.
