Nothing could better prove the complete and happy change that has taken place in this district within the last month, in the manner in which the anniversary of Tuesday last was observed. It is unnecessary to state how it was kept in former years. The last 12th, however, was observed not as a holiday, but as a holy day — as a solemn Sabbath, which commenced, continued and ended in praise prayer and other religious worship.
"In the forenoon, the brethren who met in Dundrod came to the hall with their Bibles in their hands and waited on Mr McGill with the request that he would go to their place of meeting and engage in religious worship with them and others assembled. This request was cheerfully complied with. In the evening, by special request, a prayer meeting was held in Dundrod at six o'clock. The Orangemen from the surrounding district came in great numbers, without either music, banners or any party badge. They arrived as solemn, serious men going up to worship God in His sanctuary. They had nothing to distinguish them as Protestants but their Bibles, which they carried in their hands. The numbers assembled were so great that the large church could not hold them, and the meeting was held in the open-air, in an enclosed garden in the rear of a schoolhouse. The greatest order, solemn and deep seriousness prevailed during the whole service, which lasted about two hours among the vast assembly of about twelve hundred men. “The people afterwards, who separated, went home in groups wondering at the strange ‘twelfth’ they had witnessed, and blessing God for the privilege and pleasure enjoyed throughout the day. Not an oath, not an insulting word, not a party expression issued from the lips of man or woman was seen or heard throughout the whole day.

I do not know which hall they are referring to.
