 Arrival of the North Star.
 The steamer North Star Captain Minor, ar rived yesterday from Aspnwall, whence she sailed on the 14th inst. She did not connect with any California steamer, and therefore brings no later advices from that quarter.
 The Cyane left at Carthagena, on the 18th inst, French squadron of six sail, consisting of three steam sloops, the frigate Iphigenia, and two twenty gun brigs. They were there for the purpose of enforcing claim for sixty thou sand dollars, made by French subject, for flour destroyed by order of President Herrera few years ago.
 There were five thousand men engaged at work on the Panama railroad; that force would be kept at work until the track be finished to Panama. The track to the Summit will be in readiness for the cars by the middle of May, which will leave but eleven miles of a good mule road to Panama All the main points of difference between the Panama railroad compa- ny and the provincial government have been settled, except few, which are to be referred to higher powers.
 There was great rush of passengers from Australia to Peru, in consequence of reports cir 
 mense Jumps of gold on the banks of the Anna ZOn.
 THE SAFETY OF LIEUT.. STRAINS PARTY.
 U. s. SHIP CYANE
 Aspina0aU April IA, 1854.
 We arrived here this morning from Cartha- gena, in thirty hours. At Az o'clock P. M. this day Lieut.. Charles M Fauntleroy arrived from Panama with the joyful intelligence of the safety of Lieut. Strain and fifteen of his party, after enduring innumerable hardships and sufferings. Lieut.. Strain and one or two others of his command were to return on the 16th from Panama, and bring the remainder to this place, from whence they will proceed to the United States in the steamer.
 Lieut.. Fauntleroy pursued his investigations alone in the Chepo country, and Is now suffer- ing from severe illness and fatigue. Four of the seamen belonging to this ship, and the two Spanish commissioners, are reported by Lieut. Strain as having died in consequence of the severe hardship, which they endured
 THE AMAZON GOLD MINEs-THE RUSH FROM
 AUSTRALIA.
 From the Lima News March 25th.
 The English ship Launceston, Captain Belts. arrived in the port of Callao on the 18th inst, in the remarkably short space of thirty days as reported in the custom house-from Laun- ceston Heads.
 The Launceston brought one hundred and elghty-three paSsengers--mOst of whom are bound for the mines on the Amazon. They report that great excitement exists in Australia, regarding these mines. The Launceston's pas senger list was filled in less than twenty four hours after being advertised
 The following named vessels-not yet arriv- ed-left Melbourne for Callao previous to the icaiI Cf II. bourne Packet Akabar Amartha, Emily Minor
 The steamer of tomorrow will carry a large number of passengers to Huanchaco, where they will debark for the mines, via Chachapoy- as, Moyobamba, etc. We have endeavored to learn the exact number who intend leaving but have been unsuccessful. About seventy, how ever, engaged passage on Tuesday last, and we suppose the number has increased since then to near one hundred.
 From reports of passengers by the Launces- ., ton, we shall have an immense emigration to thls country from Australia within the next three or four months. The stories of ''twenty- five pound lumps' found on the Amazon, have had similar effect in Australia to the first news received ln the U nted States of the discovery of gold in California. It is difficult to judge correctly, from so many different reprots, the probable number who will soon arrive here Some say 5OOO-others, 3O OOO but we imagine the former to be nearer the mark Many of them will no doubt be greatly disappointed- They will arrive here expecting, at least, to find good road opened to the reported mines. But in place of that they will learn-so little interest is here taken in the matter-that not single river has been bridged, not single moun- tain trail been improved
 Since writing the above, we have learned that party of natives have for some time past been working on the trail beyond Moyobamba As we understand there is a good mule road from the coast to that place, parties will proba- ply experience no difficulty in going clear through to the headwaters
 NAVIGATION OF THE AMAZON.
 A correspondence relative to the free naviga- tion of the Amazon, has recently taken place between the English charge d'affars to this country and the Peruvian minister of foreign affairs. The English minister receives similar answer as that given to MT. Clay-that the treaty between Peru and Brazil gives the for mer government privileges and advantages in the waters of Peru, not allowed to any other nation.
 Such an answer was to have been expected. though 1t IS we'll known that the government of Peru earnestly desires the free navigation of that river. There never was more forcible illustration of the dog and manger'' fable than this same question presents: Brazil holding the key of the finest country in the world, de- cllnes opening the gate herself, and is not dis posed to allow the privilege to others. But at this day such churlishness will not be tolerated. Brazil can boast of little strength, and in case like this, might makes rght''
