This is an excerpt from the monthly account by the Salvation Army station here.
Time and space will not allow us to give all the dear brethren and sisters testimonies, but we are very thankful to say that God has saved about 180 precious souls. Believers have been quickened. They tell us we have brought some of the London fire, but it is not us, it is God, the Holy Ghost. We held our first holiness meeting on May 10th. We get the hall crowded every night and we get from fifty to sixty brethren and sisters to help us for an hour and a half in the open air on Sunday morning.
From, 'The Christian Mission Magazine', June 1878, pages 166-7.
ONWARD and upward, Salvation and Holiness. The devil had people prophesying all manner of bad about us. Since Brother Morrison came amongst us we are rising, and today we are stronger and in better health than ever we were. On Sunday night we had the best open-air meeting that we ever had in Felling. Hallelujah. During the past week we have had 18 souls saved. To God be all the glory.
From 'The Salvationist', March 1879, page 73.
Still going on, if one wants to see future reports, see 'The War Cry', which began January 1880.
I do not know where the meetings were held.
