It has been stated that the Survey of the Mexican Boundary Commission was progressing rapidly westward. The astronomers and surveyors of the American and Mexican Commissioners had joined forces, and their advanced parties had reached a point thirty miles west of Rio Mienlies. The line was to run eight or ten miles south of Cooks Spring, thus giving the United States the whole of the road to the Copper Mines, and the only route which can be traversed by wagons. We have later intelligence, that in consequence of a disagreement between the Commissioners and the Surveyor, the operations of the Commission are almost suspended.

Dr. Gardner, of fraudulent Mexican claim notoriety, has returned to Washington, surrendered himself into the hands of the United States authorities, and given bail in the sum of $40,000 to appear for trial at the December term. Senator Chase, of Ohio, has issued a manifesto in which he announces his intention to adhere to the platform and support the ticket of the Ohio Democratic Convention. But the ground of this determination is, that he considers the action of that Convention, besides being acceptable on other topics, as in effect indorsing the Free Soil doctrines. John McPherson Berrien has declared his intention of acting with the Union party. Gen. Quitman, before the late election, withdrew from the contest, as the secession candidate for Governor of Mississippi. The Special Convention of the Protestant Episcopal Church for the election of an Assistant Bishop fur the Diocese of Illinois, was held at Pekin, Sept. 8, and resulted in the election of Dr. Whitehouse, of New-York. The annual meeting of the American Board of Commissioners for Foreign Missions was held at Portland, on the 9th day of September. The President, Theodore Frelinghuysen, presided, and the affairs of the society and its prospects, were presented in several very interesting reports.

In the last number of this magazine, we stated the failure of some ineffectual risings in CUBA, and supposed that the peace of that island was reestablished, at least for a considerable period. But, about the end of August, the country became exceedingly interested respecting the fate of the steamer Pampero, which, it had become known, had left New Orleans with several hundred men, under the command of General Narciso Lopez, with the intention of landing at some point on the Cuban coast. It afterwards was disclosed that the party, which consisted of 480 men, designed to go to the River St. John, and effect a junction with an artillery force which was waiting there, and then land at some point in the central department; but on touching at Key West for stores, they were informed of a revolt of the Vuelta de Abajo, and Lopez resolved to land in that district. The party disembarked at the small town of Morillos, at two o'clock, on the morning of the 12th of August; and, soon after, General Lopez sent a pronunciamento to Los Pazos, in which he informed the inhabitants he was about to march on them, and would give no quarter to any who did not join him. Being without means of transportation, he ordered Colonel Crittenden to remain and protect the baggage, together with 1000 musket cartridges, 3000 muskets, and 700 pounds of powder in kegs. He told Crittenden that he would send for him at Los Pazos, and took with him 323 men, leaving 130 with Crittenden, who, at 11 o'clock that night, started to rejoin him. Their advance was slow, and on the morning of the 13th, while eating breakfast, they were surprised by a report of musketry, and the whistling of bullets, from a body of the enemy, who were repulsed with a loss of nine killed. A short time after they repeated the attack. Crittenden charged, and forced them to retreat to a chaparral, from which, as the invaders advanced, they opened a destructive fire. Finding he could not maintain his position, Crittenden ordered a return, and the enemy again advanced. At this time, he wished a small party to attain a position at the right flank of the enemy, to charge from that side at the same moment he charged on the front. Lieutenants Van Vechten and Crafts, with twenty men, volunteered, and attained the position. After remaining about half an hour, and hearing nothing of Crittenden, they were compelled to retreat, leaving their baggage and stores. The next morning this party succeeded in joining Lopez at Los Pazos, half an hour before he marched from that place. Gen. Enna, commander of the Spanish troops, immediately attacked Lopez with 800 men. After a hard fight, the enemy retreated, leaving a large number (among whom were several of their highest officers) dead and wounded. Lopez lost in killed and wounded, thirty men, among whom were Col. Dowzeman, Lieut. Laviseau, killed; Gen. Pragay, Capts. Brigham and Gonti, mortally wounded. On the morning of the 14th, Lopez marched into the mountains, and on that day he was attacked by 900 men. The action lasted three hours, and the Spaniards retreated with a large loss. At the moment that the Spaniards retreated in one direction, Lopez issued an order to retreat in an opposite one, and made a forced march of 18 miles in 5 hours, over a mountain road. On the 19th, being still in the mountains, two leagues from Bahia, he was overtaken by a heavy rain storm, which destroyed the greater part of his ammunition, and rendered the firearms entirely useless. On the morning of the 20th, the sentry was surprised and shot, and Lopez was completely routed, flying to the mountains. Lopez escaped on horseback, with nothing but what he wore. He encamped on one of the mountains, exposed to the violence of a terrific storm. On the evening of the 21st, having been forty-eight hours without food, a horse was killed and divided among 125 men, who were all that remained with him. They wandered about until mid-day of the 24th, when a halt was ordered, and on examination it was found that they had only 60 serviceable muskets, and about 40 dry cartridges. They commenced a retreat, when a force of 900 charged on the party. They dispersed, threw away their arms, and fled to the mountains; seven men only remaining with Lopez, and a large number being overtaken and killed. Lopez was taken with six of his men in the Pinos de Rangel; his captors were Jose Antonio Castañeda, guide of a pursuing force, and fifteen peasants of the country. The capture took place on the 29th, just seventeen days from his landing. The news of it spread at once through the country, and people began to flock into the camp to see the prisoners; to avoid inconvenience, Col. Ramon de Lago, who commanded the column, conveyed them to Havana by a night march.

The second day after being separated from Lopez, the party under Colonel Crittenden was captured by a detachment of Spanish soldiers and carried into Havana, where, on the sixteenth of August they were shot, by order of the Captain General. Very much exaggerated accounts of the circumstances attending their execution were circulated in the United States; and by forged letters respecting successes by the invaders, adhesions to them by the people of the island, indignities to Americans, &c., it was sought to excite the public indignation so that further expeditions should be set on foot that would be altogether irresistible. The party whose managements consisted of such systematic and persevering falsehood lost all its energy when news came of the capture of Lopez and the remnants of his army. At seven o'clock on the morning of the first of September, Lopez was garroted—that being the Spanish punishment for treason—in the presence of from eight to ten thousand troops. Brought from the prison he ascended the platform with a firm and steady step. Facing the multitude he made a short speech, and his last words were, "I die for my beloved Cuba." He then took his seat—the machine was adjusted; at the first twist of the screw his head dropped forward—and he was dead. He was a brave man, but of feeble capacities, and the leading members of the Cuban junta in the United States had no confidence in any movements subject to his direction. A few of the prisoners taken about the time of the capture of Lopez have been set at liberty, and others have been transported to Spain. The result of the whole business shows that the bodies of the prisoners shot at Havana with Crittenden and Kerr, were not mutilated nor anywise maltreated, as had been stated, but that the story that they had been was fabricated to excite indignation and procure reinforcements in this country; that the invaders achieved no important success at any time, beyond the killing of General Enna and the consequent repulse of the detachment led by him; that they killed not more than two hundred of the Spaniards; that they at no time were able to act on the offensive, but fought for their lives from the first, and were at length surprised and utterly routed; that, though they were landed in the very quarter of Cuba where Lopez was most likely to obtain aid, yet they received none of any kind, and were not joined by a single corporal's guard from the hour of their setting foot on the soil of Cuba; that the Creoles, or natives of Cuba, so far from affording them such aid as even cowards friendly to them might safely have done, evinced the most active and deadly hostility throughout to the invaders and their cause. We cannot doubt that they furnished the information which led to the surprise and route of Lopez; we know that they finally deceived, betrayed, bound and delivered him to Concha.

The Canadian Parliament was prorogued by the Governor-General on Saturday, the 30th of August, to the 8th of October. The royal speech represents the revenue as in a satisfactory state, and refers to the grants for improving the navigation of the St. Lawrence, and to the reduction of the emigrant tax. Six bills were reserved for the approval of the Queen, three of which relate to churches and rectories, two to the reduction of salaries, and one to the incorporation of the Fort Erie and Buffalo Suspension Bridge Company. The reciprocity question was left unsettled. The paraphernalia of the Canadian Government has since been removed from Toronto to Quebec. The general election in the Province of Nova-Scotia for members of Parliament, has resulted in a majority for the existing Government. The Provincial Secretary, the Attorney-General, the Financial Secretary, leading members of the Cabinet, have been reëlected. The construction of the railway from Halifax to Portland, and through New-Brunswick to Quebec, may be considered as secured. The question has been one of the prominent points in the election—the Liberals being in favor of, and the Conservatives opposed to it.

The Mexican Congress have passed a bill for the formation of an alliance, offensive and defensive, between all the Spanish American republics. With a foreign debt beyond her ability to pay; with a deficit accruing every year; with a whig government, threatened by insurrection at home, and blockade from a foreign power, Mexico may well look around her for some method of prolonging her existence. Opposition continues to the Tehuantepec treaty; and it is stated that two vessels sent from New-Orleans to commence the canal were seized by the Mexican authorities.

In South America there has been more than the usual amount of revolution. The President of Ecuador, General Nueva, left Querto on the seventeenth of July, to visit his family at Guayaquil. On approaching the city he was met by a military cavalcade, apparently for the purpose of escorting him in: but was seized by them, and hurried off to sea in a vessel lying in the river; the destination of the vessel, and the fate of the prisoner were unknown. General Urbina immediately entered upon the administration of affairs. In Chili, Don Manuel Montt has been elected President by a large majority. Advices from Montevideo to July thirtieth, state that Urguiza and Garzon passed the Uraguay on the twentieth with seven thousand five hundred men, and that General Servando Gomez at once went over to them from the army of Oribe with two thousand cavalry, some staff officers and one thousand extra horses. It is expected that all of Oribe's forces will desert him in the same manner. Garzon, who formerly served with Oribe, is very popular among his forces. A Brazilian army of twelve thousand men is marching to join Urguiza and Garzon. The war will now be carried into the territories of Buenos Ayres. It will doubtless be a most ferocious contest; with Rosas it is a matter of life and death; the power he has built up with such bloodshed and tyranny will either be destroyed utterly or confirmed by the result. In Peru, the best understanding is said to exist between the Legislative and Executive bodies in the Government. Movements are being made for the greater extension of freedom of trade, and for prohibiting the circulation of Bolivian money within the Republic.

A revolution has broken out in the provinces of Antiochia and Popayan, in New-Grenada, which at the last advices (July twenty-fourth), was rapidly spreading over the country. The rising is headed by General Borrero, who took up arms with one thousand men, and has since received large accessions to his forces. General Borrero has the reputation of being an accomplished soldier and a sincere patriot. The city of Carthagena was thrown into great confusion by the reception of the intelligence, the militia being called out and the people supplied with arms.

In Nicaragua a revolution has displaced the government, and M. Montenegro, who was elected successor of the deposed President, died in a few days after, and the chief of the opposite faction, General Muños, is probably now in authority.

From Great Britain the news is various but generally of small importance. The Queen and Royal Family have been making a tour in Scotland, which gave occasion to the usual rejoicings and demonstrations of loyalty. The most grave questions discussed in the journals are connected with the Roman Catholic Disabilities subject. On the 19th August a great gathering of the Roman Catholic clergy and laity took place at the Rotunda in Dublin. The object in view was the organization of a party and the commencement of an agitation to bring about the repeal of the obnoxious act of Parliament. So strongly was public feeling excited on the occasion, that the military and police forces were held in readiness for action. Fortunately the peace was not disturbed; although the spiritual leaders themselves boldly set the law at defiance by the use, in one of their resolutions, of the very titles prohibited by the recent enactment. Among the notices of motion that have been placed on the books of the House of Commons for "next session," is one by Mr. Hume to move that "after a day to be fixed by Parliament, no person, male or female, shall be admitted to the service of the public, in any permanent civil office or department, unless they shall pass an examination by competent persons appointed for that purpose, and shall be found capable of fluently reading and writing the English language". In England the Railway Companies have held their annual meetings. The increase of travel has not kept pace with the increase of railways; the average profit is 3 per cent. The Times has had some forcible articles recently on the possibility of running a railroad straight from London to Constantinople, and thence through Ask Minor to India, so as to make Calcutta accessible in seven days. This the Times describes not only as practicable, but even of probable accomplishment, in a given number of years.
