Task: Question Answering
Input (English): Passage: Between 9:00 pm and 10:00 pm the guards enacted a strategy whereby the police officers, backed by the bayonets of the soldiers, advanced to the crowd and arrested each a man, who was then taken into the station, disarmed, and held there. The strategy was largely successful, and by 11:00 pm the area around the station was mostly cleared, though sporadic gunfire could be heard throughout the night. Between 165 and 200 were detained in total, and the most violent of the captives were removed and taken to the police station. The news reported that four, including one police officer, were injured in the exchange, and several who resisted arrest were beaten severely.At the foundry near the Carey Street Bridge, a crowd of more than 100 gathered and threatened to set fire to the area. A contingent of the 5th under Captain Lipscomb arrived, and a volley fired over the heads of the crowd was sufficient to dissuade the crowd. An unsuccessful attempt was also made to burn a B&O transportation barge at Fell's Point. The news reported that 16 were arrested in a confrontation between citizens and the police at Lee and Eutaw, and that during the night, three separate attempts were made to set fire the 6th Regiment armory, but all were frustrated by the remaining garrison there.Just before midnight, 120–135 marines arrived at the station and reported to the governor, who ordered them to set about capturing the leaders of the mob. Governor Carroll telegraphed and advised President Hayes that order had been restored in the city.
Between 2:00 am and 3:00 am on Sunday morning, July 22, the peace was again broken and fire alarms began to ring throughout the city. To the west, at the Mount Clare Shops of the B&O, a 37-car train of coal and oil had been set on fire. Police, firefighters, and thousands of citizens flocked to the scene. A contingent of 50 marines was dispatched to the area to provide assistance. The cars which had not yet caught fire were detached from those burning, and by the time the flames were extinguished between seven and nine cars had been burned. Between $11,000 and $12,000 in damage was sustained.At 4:00 am another alarm sounded: the planing mills and lumber yard of J. Turner & Cate near the Philadelphia Wilmington & Baltimore rail depot, had been set on fire. The entire property, extending over a full city block, was destroyed. Realizing the severity of the situation, the firefighters concentrated their efforts on trying to save the surrounding structures.According to news reports, the first passenger trains left the city at 9:00 am, and continued running throughout the day. Around 10:00 am, General W. S. Hancock arrived and was followed by 360–400 federal troops from New York and Fort Monroe, who relieved those guarding Camden Station. They brought with them two 12 pounder artillery pieces. From that point on, the men of the 5th and the federal troops took turns guarding the station. 
Question: At what time was the lumber yard of J. Turner & Cate set on fire on the day where a car train of coal was set on fire?
Output (English): 4:00 am.
