_Extracted from the Kensington News._--Amidst the various styles of ecclesiastical architecture which our modern amalgamation of various civilizations has produced, none strikes one as so peculiar as that which is called the preaching tent. Associated as this moveable structure is with the wandering life of the Eastern Arab, its consecration to purposes of modern Christian evangelization is a proof of the intense catholicity and energy of our modern religious life. While thousands of our home heathen never enter the sacred precincts of our churches or chapels, it is a blessing to find that they enter by hundreds inside the temporary canvas walls of our consecrated gospel tents. Very often the surroundings of the locality where these places are erected, the kind of services held in them, and the earnestness, homeliness, humanity, and appropriateness of the illustrations of the preachers who discourse at them, have beyond question, great attractions for the class of our Metropolitan inhabitants just mentioned. It calls for no surprise to find gigantic temporary structures of this kind erected amidst the uncultivated and populous "East" for the purposes of religious worship, but we hardly expect to find their tapering canvas roofs amidst the luxury of the "West." But in these days of change, and strange things, we are not easily surprised, and consequently we passed by gospel tents at Kilburn and Kentish Town without expressing much wonder. Having a desire to see how the un-church and un-chapel going population of this mighty metropolis spent their Sunday out doors, we strolled to the classic ground of Chelsea and found ourselves on the north side of the bridge. This spot has been for several years the scene of rather unclassical and disorderly debates, and open air preaching. This arena of intellectual life was rather dull on this occasion; there was only the ordinary open air service and a few groups of the usual unintelligent and sceptical wranglers. Seeing nothing worthy in what we witnessed to detain us at this place, we strolled over the bridge, towards the canvas cathedral, which has lately been erected there. Having reached the middle of the bridge, the floating banners in the distance clearly indicate the locality where this place of public worship rears its canvas walls, and as we approach nearer we find the well known words "God is Love" neatly inscribed on one of them. At this portion of the road our attention is arrested by a few of the church-going population outside the entrance to Battersea Park, gathered round some open air preachers. At last we reach the south-eastern gate of Battersea Park, opposite which is the front of the canvas cathedral a substantial tent, capable of holding about 300 people. (The tent will seat 200). We were very much surprised to find at one of the entrances a well-executed and coloured diagram of the famous Babylonish temple of the Seven Spheres. We saw from the
