One of the most marked features in the meetings has been the appearance of men who have never before taken part in public life, who have never till now stood on a public platform.

Now for the first time they have broken with the tranquil traditions of a lifetime, and have come forward to take their share and their responsibility in the grave danger which threatens their country."[10] There being no building large enough to hold the delegates, numbering nearly twelve thousand, every one of whom was a registered voter appointed by the polling districts to attend the Convention, a pavilion, the largest ever used for a political meeting in the kingdom, was specially constructed close to the Botanical Gardens in Belfast.

It covered 33,000 square feet, and, owing to the enthusiasm of the workmen employed on the building, it was erected (at a cost of over L3,000) within three weeks.

It provided seating accommodation for 13,000 people, but the number who actually gained admittance to the Convention was nearly 21,000, while outside an assemblage, estimated by the correspondent of _The Times_ at 300,000, was also addressed by the principal speakers.
The commencement of the proceedings with prayer, conducted by the Primate of all Ireland and the Moderator of the Presbyterian Church, set a precedent which was extensively followed in later years throughout Ulster, marking the spirit of seriousness which struck numerous observers as characteristic of the Ulster Movement.

The speakers were men representative of all the varied interests of the Province--- religious, agricultural, commercial, and industrial--and among them were two men, Mr.Thomas Sinclair and Mr.Thomas Andrews, who had been life-long Liberals, but who from this time forward were distinguished and trusted leaders of Unionist opinion in Ulster.
