How does Jurgis react to the tour of Durham's meat packing plant?

Jurgis was impressed by the tour.

Jurgis went down the line with the rest of the visitors, staring open-mouthed, lost in wonder. He had dressed hogs himself in the forest of Lithuania; but he had never expected to live to see one hog dressed by several hundred men. It was like a wonderful poem to him, and he took it all in guilelessly—even to the conspicuous signs demanding immaculate cleanliness of the employees.
