Hewitt hastened round to the front of the nursery garden and quietly tried first the wide gate and next the small one. Both were fastened securely. But in the manner of the milkman at the gate of the house above, Hewitt slipped his hand between the open slats of the small gate and slid the night-latch that held it. Within the quarrel ran high as Hewitt stepped quietly into the garden. He trod on the narrow grass borders of the beds for quietness’ sake, till presently only a line of shrubs divided him from the clamorous nurseryman. Stooping and looking through an opening which gave him a back view, Hewitt observed that the brushing and scraping noise proceeded, not from angry scramblings, but from the forcing through an inadequate opening in the hedge of some piece of machinery which the nurseryman was most amicably passing to his neighbour at the same time as he assailed him with savage abuse, and received a full return in kind. It appeared to consist of a number of coils of metal pipe, not unlike those sometimes used in heating apparatus, and was as yet only a very little way through. Something else, of bright copper, lay on the garden-bed at the foot of the hedge, but intervening plants concealed its shape. [Illustration: “FORCING THROUGH THE HEDGE SOME PIECE OF MACHINERY.”] Hewitt turned quickly away and made towards the greenhouses, keeping tall shrubs as much as possible between himself and the cottage, and looking sharply about him. Here and there about the garden were stand-pipes, each carrying a tap at its upper end and placed conveniently for irrigation. These in particular Hewitt scrutinised, and presently, as he neared a large wooden outhouse close by the large gate, turned his attention to one backed by a thick shrub. When the thick undergrowth of the shrub was pushed aside a small stone slab, black and dirty, was disclosed, and this Hewitt lifted, uncovering a square hole six or eight inches across, from the foreside of which the stand-pipe rose. [Illustration: THE STAND-PIPE IN THE NURSERY GARDEN.] The row went cheerily on over by the hedge, and neither Trennatt nor his neighbour saw Hewitt, feeling with his hand, discover two stop-cocks and a branch pipe in the hole, nor saw him try them both. Hewitt, however, was satisfied, and saw his case plain. He rose and made his way back toward the small gate. He was scarce half-way there when the straining of the hedge ceased, and before he reached it the last insult had been hurled, the quarrel ceased, and Trennatt approached. Hewitt immediately turned his back to the gate, and looking about him inquiringly hemmed aloud as though to attract attention. The nurseryman promptly burst round a corner crying, “Who’s that? who’s that, eh? What d’ye want, eh?” “Why,” answered Hewitt in a tone of mild surprise, “is it so uncommon to have a customer drop in?” “I’d ha’ sworn that gate was fastened,” the old man said, looking about him suspiciously.
