Read it through once

The outskirt of the garden in which Tess found herself had been left uncultivated for some years, and was now damp and rank with juicy grass which sent up mists of pollen at a touch; and with tall blooming weeds emitting offensive smells—weeds whose red and yellow and purple hues formed a polychrome as dazzling as that of cultivated flowers. She went stealthily as a cat through this profusion of growth, gathering cuckoo-spittle on her skirts, cracking snails that were underfoot, staining her hands with thistle-milk and slug-slime, and rubbing off upon her naked arms sticky blights which, though snow-white on the apple-tree trunks, made madder stains on her skin; thus she drew quite near to Clare, still unobserved of him.
