from the plant upon which it groweth. Two things therefore may be certainly set down: first, that superfætation must be by abundance of sap in the bough that putteth it forth: secondly, that that sap must be such as the tree doth excern, and cannot assimilate ; for else it would go into a bough; and besides, it seemeth to be more fat and unctuous than the ordi. nary sap of the tree; both by the berry, which is clammy; and by that it continueth green winter and summer, which the tree doth not.

557. This experiment of misseltoe may give light to other practices. Therefore trial would be made by ripping of the bough of a crab-tree in the bark; and watering of the wound every day with warm water dunged, to see if it would bring forth misseltoe, or any such like thing. But it were yet more likely to try it with some other watering or anointing, that were not so natural to the tree as water is ; as oil, or barm of drink, etc. so they be such things as kill not the bough.

558. It were good to try, what plants would put forth, if they be forbidden to put forth their natural boughs; poll therefore a tree, and cover it some thickness with clay on the top, and see what it will put forth. I suppose it will put forth roots; for so will a cion, being turned down into clay: therefore, in this experiment also, the tree would be closed with somewhat that is not so natural to the plant as clay is. Try it with leather, or cloth, or painting, so it be not hurtful to the tree. And it is certain, that a brake hath been known to grow out of a pollard.

559. A man may count the prickles of trees to be a kind of excrescence; for they will never be boughs, nor bear leaves. The plants that have prickles are

. thorns, black and white; brier, rose, lemon-trees, crab-trees, gooseberry, berberry; these have it in the bough: the plants that have prickles in the leaf are. holly, juniper, whin-bush, thistle; nettles also have a small venomous prickle; so hath borage, but harmless. The cause must be hasty putting forth, wan! of moisture, and the closeness of the bark; for the

haste of the spirit to put forth, and the want of nourishment to put forth a bough, and the closeness of the bark, cause prickles in boughs; and therefore they are ever like a pyramis, for that the moisture spendeth after a little putting forth. And for prickles in leaves, they come also of putting forth more juice into the leaf that can spread in the leaf smooth, and therefore the leaves otherwise are rough, as borage and nettles are. As for the leaves of holly, they are smooth, but never plain, but as it were with folds, for the same cause.

560. THERE be also plants, that though they have no prickles, yet they have a kind of downy or velvet rind upon their leaves; as rose-campion, stock-gillyflowers, colt's-foot; which down or nap cometh of a subtile spirit, in a soft or fat substance. For it is certain, that both stock-gilly-flowers and rose-campions, stamped, have been applied with success to the wrists of those that have had tertian or quartan agues; and the vapour of colt's-foot hath a sanative virtue towards the lungs; and the leaf also is healing in surgery.

561. ANOTHER kind of excrescence is an exudation of plants joined with putrefaction; as we see in oak-apples, which are found chiefly upon the leaves of oaks, and the like upon willows: and country people have a kind of prediction, that if the oak-apple broken be full of worms, it is a sign of a pestilent year; which is a likely thing, because they grow of corruption.

562. THERE is also upon sweet, or other brier, a fine tuft or brush of moss of divers colours; which if you cut you shall ever find full of little white worms.

Experiments in consort touching the producing of perfect plants without seed.

563. It is certain, that earth taken out of the foundations of vaults and houses, and bottoms of wells, and then put into pots, will put forth sundry kinds of herbs: but some time is required for the germination: for if it be taken but from a fathom deep, it will put forth the first year; if much deeper, not till after a year or two.

564. The nature of the plants growing out of earth so taken up, doth follow the nature of the mold itself; as if the mold be soft and fine, it putteth forth soft herb; as grass, plantain, and the like; if the earth be harder and coarser, it putteth forth herbs more rough, as thistles, firs, etc.

565. It is common experience, that where alleys are close gravelled, the earth putteth forth the first year knot grass, and after spire grass. The cause is, for that the hard gravel or pebble at the first laying will not suffer the grass to come forth upright, but turneth it to find his way where it can; but after that the earth is somewhat loosened at the top, the ordinary grass cometh up.

566. It is reported, that earth being taken out of shady and watery woods some depth, and potted, will put forth herbs of a fat and juicy substance; as

a penny-wort, purslane, housleek, penny-royal, etc.

567. The water also doth send forth plants that have no roots fixed in the bottom; but they are less perfect plants, being almost but leaves, and those small ones; such is that we call duck-weed, which hath a leaf no bigger than a thyme leaf, but of a fresher green, and putteth forth a little string into the water far from the bottom. As for the water lily, it hath a root in the ground; and so have a number of other herbs that grow in ponds.

568. It is reported by some of the ancients, and some modern testimony likewise, that there be some plants that grow upon the top of the sea, being supposed to grow of some concretion of slime from the water, where the sun heateth hot, and where the sea stirreth little. As for alga marina, sea weed, and eryngium, sea thistle, both have roots; but the sea weed under the water, the sea thistle but upon the shore.

569. The ancients have noted, that there are some herbs that grow out of snow laid

up

close together and putrefied, and that they are all bitter; and they name one specially, flomus, which we call moth-mullein. It is certain, that worms are found in snow

а

commonly, like earth-worms; and therefore it is not unlike, that it may likewise put forth plants.

570. The ancients have affirmed, that there are some herbs that grow out of stone; which may be, for that it is certain that toads have been found in the middle of a free-stone. We see also that flints, lying above ground, gather moss; and wall-flowers, and some other flowers, grow upon walls ; but whether upon the main brick or stone, or whether out of the lime or chinks, is not well observed : for elders and ashes have been seen to grow out of steeples; but they manifestly grow out of clefts; insomuch as when they grow big, they will disjoin the stone. And besides, it is doubtful whether the mortar itself putteth it forth, or whether some seeds be not let fall by birds. There be likewise rock-herbs; but I suppose those are where there is some mold or earth. It hath likewise been found, that great trees growing upon quarries have put down their root into the stone.

571. In some mines in Germany, as is reported, there grow in the bottom vegetables; and the workfolks use to say they have magical virtue, and will not suffer men to gather them.

572. The sea sands seldom bear plants. Whereof the cause is yielded by some of the ancients, for that the sun exhaleth the moisture before it can incorporate with the earth, and yield a nourishment for the plant. And it is affirmed also that sand hath always its root in clay; and that there be no veins of sand any great depth within the earth.

573. It is certain, that some plants put forth for a time of their own store, without any nourishment from earth, water, stone, etc. of which vide the experiment 29.

Experiments in consort touching foreign plants.

574. It is reported, that earth that was brought out of the Indies and other remote countries for ballast of ships, cast upon some grounds in Italy, did put forth foreign herbs, to us in Europe not known; and, that which is more, that of their roots, barks, VOL. I.

2 F

and seeds, contused together, and mingled with other earth, and well watered with warm water, there came forth herbs much like the other.

575. Plants brought out of hot countries will endeavour to put forth at the same time that they usually do in their own climate ; and therefore to preserve them, there is no more required, than to keep them from the injury of putting back by cold. It is reported also, that grain out of the hotter countries translated into the colder, will be more forward than the ordinary grain of the cold country. It is likely that this will prove better in grains than in trees, for that grains are but annual, and so the virtue of the seed is not worn out; whereas in a tree it is embased by the ground to which it is removed.

576. Many plants which grow in the hotter countries, being set in the colder, will nevertheless, even in those cold countries, being sown of seeds late in the spring, come up and abide most part of the summer; as we find it in orange and lemon seeds, etc. the seeds whereof sown in the end of April will bring forth excellent sallads, mingled with other herbs. And I doubt not, but the seeds of clove-trees, and pepper seeds, etc. if they could come hither green enough to be sown, would do the like. E.rperiments in consort touching the seasons in

which plants come forth. 577. THERE be some flowers, blossoms, grains, and fruits, which come more early, and others which come more late in the year. The flowers that come early with us are primroses, violets, anemonies, waterdaffadillies, crocus vernus, and some early tulips. And they are all cold plants ; which therefore, as it should seem, have a quicker perception of the heat of the sun increasing than the hot herbs have; as a cold hand will sooner find a little warmth than a hot. And those that come next after, are wall-flowers, cowslips, hyacinths, rosemary flowers, etc. and after them pinks, roses, flower-de-luces, etc. and the latest are gilly-flowers, holyoaks, larksfoot, etc. The earliest
