Senator PEARCE (Western Australia) (Minister of Defence) . - It is not clear whether " Heads " mark the limitation of a port, but the word " miles," as used, means land miles. The honorable senator will- see that "except as otherwise prescribed," the provision is not to apply: to steamers trading between ports less thai* 200 miles apart; but it is intended, if thisBill becomes law, to prescribe that tha. trade between Launceston and! Melbourne shall come under this provision, the reason, being that a vessel midway between Tasmania and Australia is out of the ordinary trade route, and is as much isolated as it she were in the Indian Ocean. The necessity of such a case for wireless apparatus is as great as it would be in connexion, with any other trade. 1 move -
