During the day (Sunday) a car load of whisky or high wines was broken open by the mob, and they drank very freely of it, and towards night, at the time the Union depot and elevator were burned, most of the active rioters were so drunk as to be unable to continue the work of destruction, if they had been so disposed. Whisky had done good service in this case, if never before. The fatigue consequent upon the labors of Saturday night and Sunday was also producing its effect upon the rioters, and taken in connection with the fact, that most of them must have been filled to satiety with rioting and destruction of property, shows a good cause for the waning of the riot on Sunday afternoon. A few of the rioters, between five and six o'clock, P.M., went to the Duquesne depot, (the property of the Pennsylvania Railroad Company,) at the junction of the Allegheny and Monongahela rivers, with the intention of burning it and the cars in the vicinity. One car was set on fire and an attempt made to set the depot on fire, but some six or eight of the citizens' safety committee arrived there about the time the rioters did, and they interfered at once to put a stop to destruction, and had no difficulty in doing so, as the rioters desisted and left as soon as they saw any authority exerted in opposition to their schemes.

The Eighteenth regiment (Colonel Guthrie) had remained at Torrens station, keeping the track clear at that point, and waiting for the expected trains. The crowd at that place numbered about fifteen hundred men, composed of mill men, some railroad men, boys, roughs, and tramps. The passenger trains were allowed to run by the mob, but between Pittsburgh and Torrens they were filled to overflowing by the roughest of the crowd, who traveled backwards and forwards between those places on the trains at their pleasure, and no one dared to interfere with them. They even climbed on the engine and tender, and roofs of the cars, and controlled the movements of the trains whenever they chose so to do between those two points. At Torrens, the crowd would occasionally become demonstrative and defiant, and Colonel Guthrie was obliged to charge bayonets on them several times, and each time had no difficulty in dispersing them. Twice he ordered his men to load in presence of the crowd, and this of itself dispersed them. Colonel Guthrie's troops were not allowed to fraternize with the mob, but were kept entirely aloof from them, and this regiment does not seem to have become demoralized, as the Fourteenth and Nineteenth regiments were. About four o'clock, P.M., Sunday, Colonel Guthrie, hearing that the Fourteenth and Nineteenth regiments had been disbanded, and being unable to ascertain the exact condition of affairs at Pittsburgh, went there and consulted with General Latta, and his regiment was ordered to march to that place, where they arrived about dark, and, of course, too late to be of any service in stopping the destruction of property, which had all taken place before their arrival. They marched to the armory and stayed all night, and on Monday forenoon, the Twenty-third, together with the Fourteenth and Nineteenth regiments, which had been ordered to reassemble that morning, marched through the principal streets of the city for the purpose of overawing any riotous disposition that might still remain in those who had been engaged in the work of destruction the day before. Colonel Guthrie assumed command of the division, his commission being older than Colonel Gray's or Colonel Howard's, and when General Brown wished to assume command Colonel Guthrie refused to recognize his authority, on account of the manner in which he had managed matters on Saturday, the 21st. On Saturday night, a few of the leading citizens had suggested to the mayor that it would be well to call out all of the old police force that had been discharged, and in accordance with this suggestion the chief of police caused a notice to be published, calling on them to report at his office and they would be assigned to duty. During the day several reported and were employed, and afterwards most of the old force were taken back and assigned to duty for a time. This extra force, together with the force of citizens organized for the purpose, patrolled the city that Sunday night, and succeeding nights, until the danger had passed.

From the first commencement of the strike, the strikers had the active sympathy of a large portion of the people of Pittsburgh. The citizens had a bitter feeling against the Pennsylvania Railroad Company on account of, as they believed, an unjust discrimination by the railroad company against them in freight rates, which made it very difficult for their manufacturers to compete successfully with manufacturers further west, and this feeling had existed and been intensified for years, and pervaded all classes. A large portion of the people also believed that the railroad company was not dealing fairly by its men in making the last reduction in wages, and the tradesmen with whom the trainmen dealt also had a direct sympathy with the men in this reduction, for its results would affect their pockets.

The large class of laborers in the different mills, manufactories, mines, and other industries in Pittsburgh and vicinity, were also strongly in sympathy with the railroad strikers, considering the cause of the railroad men their cause, as their wages had also been reduced for the same causes as were those of the railroad men, and they were not only willing but anxious to make a common fight against the corporations. This feeling of aversion to the railroad company and sympathy with the strikers was indulged in by the Pittsburgh troops to the same extent that it was by the other classes, and as many of them had friends and relatives in the mob, it is not much to be wondered at that they did not show much anxiety to assist in dispersing the crowd and enforcing the law.

With the repulse of the attempt to set fire to the Duquesne depot ended all active efforts by the mob to destroy property, and after that Sunday night no mob of any size was again assembled, although it was several days before complete order was fully restored, as the people had lost confidence in all the laboring men, and no one knew who to trust or what to expect from others on account of the extent to which the demoralization had gone.

About sixteen hundred cars, (mostly freight,) including passenger and baggage cars, with such of their contents as were not carried away by the thieves; one hundred and twenty-six locomotives, and all the shops' materials and buildings, except one or two small ones, of the railroad company, from above Twenty-eighth street to the Union depot, were burned on that Saturday night and Sunday.

It has been estimated, by a competent person, that the damage, including loss of property and loss of business, consequent upon the interruption of business, which was inflicted by the mob, at Pittsburgh alone, was $5,000,000. This may be a large estimate, but if the consequential damages could be correctly arrived at, the total damage would fall but little short of the figures given. The actual loss of property by the railroad company alone, not including the freight they were transporting, is estimated at two million dollars, by the officers of the company, from actual figures made. The authorities of Allegheny county adopted thorough measures to ascertain the extent of the loss of property, and to that end appointed a committee to investigate claims of those claiming damage. One hundred and sixty-nine claims were settled by the committee, that is, the amount of each claim of this number was adjusted and agreed upon by the committee and the parties, and the total amount thus adjusted is about one hundred and sixty thousand dollars, and all this is strictly private property. Some persons refused to adjust the amount of their claims with the committee, among which is the claim of the elevator company, amounting to the sum of two hundred thousand dollars. Property that was stolen was also recovered and returned to the railroad company, amounting in value to at least sixty thousand dollars.

The tracks from Union depot out to and beyond Twenty-eighth street were nearly all ruined by the fire, the rails being warped and twisted and the ties burned; they were also covered with the debris of the burned cars, and it was about a week after the destruction, or until July 30th, before the railroad company were enabled to get their trains all running regularly again over this portion of the track.

During the troubles of the 20th and 21st, efforts were made by the strikers to come to an understanding or compromise with the railroad officials, and a committee to confer with the officials was appointed.

Some time on Friday, the 20th, the committee met Mr. Pitcairn, the superintendent of the Pittsburgh division, and presented him with a written statement of the demand made by the strikers, of which the following is a copy, viz:
