"The ancient church of Corhampton, near Bishops Waltham, in Hampshire, is an instance. This Saxon church, 1300 years old, was in a sadly dilapidated condition. In the west gable there were large cracks, one from the ridge to the ground, another nearer the side wall, both wide enough for a man's arm to enter; whilst at the north-west angle the Saxon work threatened to fall bodily off. The mortar of the walls had perished through age, and the ivy had penetrated into the interior of the church in every direction. It would have been unsafe to attempt any examination of the foundations for fear of bringing down the whole fabric; consequently the grouting machine was applied all over the building. The grout escaped at every point, and it occupied the attention of the masons both inside and outside to stop it promptly by plastering clay on to the openings from which it was running.
"After the operation had been completed and the clay was removed, the interior was found to be completely filled with cement set very hard; and sufficient depth having been left for fixing the flint work outside and tiling inside, the result was that no trace of the crack was visible, and the walls were stronger and better than they had ever been before. Subsequent steps were then taken to examine and, where necessary, to underpin the walls, and the church is saved, as the vicar, the Rev. H. Churton, said, 'all without moving one of the Saxon "long and short" stones.'"

In our chapter on the delightful and picturesque old bridges that form such beautiful features of our English landscapes, we deplored the destruction now going on owing to the heavy traction-engines which some of them have to bear and the rush and vibration of motor-cars which cause the decay of the mortar and injure their stability. Many of these old bridges, once only wide enough for pack-horses to cross, then widened for the accommodation of coaches, beautiful and graceful in every way, across which Cavaliers rode to fight the Roundheads, and were alive with traffic in the old coaching days, have been pulled down and replaced by the hideous iron-girder arrangements which now disfigure so many of our streams and rivers. In future, owing to this wonderful invention of the grouting machine, these old bridges can be saved and made strong enough to last another five hundred years. Mr. Fox tells us that an old Westmoreland bridge in a very bad condition has been so preserved, and that the celebrated "Auld Brig o' Ayr" has been saved from destruction by this means. A wider knowledge of the beneficial effects of this wonderful machine would be of invaluable service to the country, and prevent the passing away of much that in these pages we have mourned. By this means we may be able to preserve our old and decaying buildings for many centuries, and hand down to posterity what Ruskin called the great entail of beauty bequeathed to us.
