NEW YORK,• AUG. 9.  (Per Etna, via Roche's Point.)  General Burnside's whole command is said to be at Fredericksburg. He will operate with Pope, but whether their destination is Richmond or an other point is not known. The heat has become so intense within the last few days that military operations are materially retarded.  The Federal fleet below Savannah is momentarily expecting an attack from a powerful Confederate ram completed at Savannah. The land forces at Hilton Head aro also expecting an attack from the Confederates, who are in force at Bluffton. The whole Federal army is moving forward in the Virginia Valley, Fighting is rumoured to have taken place at Gordons-ville.  The Federal General M'Cook has been shot by guerillas in Alabama, whilst travelling in an ambulance. The affair created great excitement at Nashville. Some Federal soldiers went to the neighbourhood of the occurrence, burnt some houses, and hung several men. It is rumoured that prominent Secessionists in Nashville have been shot by exasperated Unionists. The captain of the Federal vessel Adriondack (9) denies that he chased the British steamer Herald within British jurisdiction.  President Davis has issued a proclamation, stating that he should not have signed the cartel for the exchange of prisoners if he had known of General Pope's orders, which change war into in discriminate robbery and murder. He therefore orders, that if Pope or any non-commissioned cfficer of his command be captured, they shall not be treated as prisoners of war, but be held in close confinement. In the event of the murder of any unarmed citizen of the southern Confederacy, under any pretence, an equal number of commissioned officers of Pope's command will be immediately hung. The above regulation extends only to Pope's command, and as privates act in accordance with superior orders, they will be treated as prisoners of war. A Confederate invasion of Kentucky is expected. The drafting excitement continues. Many persons have been arrested while endeavouring to leave the country.  Sir Allen Napier M'Nab died on the Bth inst. at  Toronto.  The crew and passengers of the Golden Gate numbered 330, out of which 100 were saved. The fire occurred 15 miles off Manzanillo. The steamer was at once headed for shore, which was three and a half miles distant, but the fire made such rapid progress that in half an hour the upper deck fell. The steamer struck the beach soon after, and the people jumped overboard to swim ashore. The vessel burnt to the water's edge, and soon disap peared. The Jura was intercepted off Cape Race.  NEW YORK, Auo. 9 (Afternoon).  Great excitement has prevailed on board the European steamers sailing to-day. The police arrested many persons liable to drafting. Many were disguised as sailors. Several fights occurred. The Government telegraphed that all persons who had purchased tickets previous to the late order could proceed on their voyage. It is again reported that on account of sickness in Richmond the Confederate army has been removed from the city to the south side of the James River. Pestilence was reported to be raging among the inhabitants of Richmond, and hundreds were dying daily. The Etna was detained for a Queen's Messenger  from Washington. The Nova Scotian was intercepted off Cape Race on the 9th inst.
