opacious

[…] I should never have gone near the fence, under any circumstances; for I was very fond of fences, of wire fences, very fond indeed; not of walls, nor palisades, nor opacious hedges, no; but to all that limited motion, without limiting vision, to the ditch, the dyke, the barred window, the bog, the quicksand, the paling, I was deeply attached, at that time, deeply deeply attached.
