malies in the result of experiments that seemed to be otherwise inexplicable.

Several other valuable fa&ts, though not of equal importance with the foregoing, are here ascertained by fair and accurate experiments; such as, That the growth of Potatoes is altogether stopped by cutting off the ftems of the plant while green The weight of crop that would be obtained from the fame field if the potatoes were taken up at any particular period from the firft of August to the middle of Odober, and the advantages that may be derived from cultivating different kinds for particular purposes. That an ardent spirit, of a very fine quality, and in confiderable quantities, may be obtained from potatoes, with several other particulars, which we cannot pretend to enu. merate,

Our experimenter also raised potatoes from feeds, and he gives the result of his experiments and observations on that subject : He is inclined to doubt whether new varieties are to be expected from seeds. In this particular, we are convinced that he is in a mistake; but as he had made only one experiment on this head, merely to observe the general result, without adverting to minute particulars, and seems disposed to repeat the experiment with particular objects in view, we shall at present say no more on this topic, hoping to have an opportunity of returning to it on a future occasion.

The disease called the Curl, attracts also the Doctor's notice; but he has only been able to point out the errors in the former conjectures that have been offered, without substituting any thing more satisfactory.

After many hints for farther experiments, and a diversity of elucidations, he apologizes for not attempting to give any general directions for cultivating this crop; for, says he, till the particulars above specified be fully ascertained, any attempt to prescribe the best and most advantageous_mode of cultivating this valuable plant must be vain and nugatory, as contradictory facts perpetually would occur, and involve the subject in the same doubts and obscurity as at present. His aim, therefore, in this effay, has been solely to elucidate some important previous questions; and he begs that others will concur in the same purpose, by prosecuting such experiments as tend to ascere tain doubtful facts. But so much attention and care is necessary in accurately conducting experiments of this fort, that we cannot expect to hear of many who will engage in such arduous pursuits ; yet we hope the author will not find it neceffary to abate in bis own exertions. How often do we see occasion to segret that there is no public inftitution in our country for the purpose of condu&ing experiments in agriculture that cannot be easily carried on by individuals !

In a succeeding article we have an account of the Irish me. thod of cultivating potatoes in the way of Lazy * beds, by the bishop of Killaloe. It is already well enough understood in this country. Sir Thomas Beevor also, who continues to enrich this work with his elegant pen, states the result of an experiment on various sorts of potatoes, that deserves to be par. ticularly noted. The forts mentioned below were all planted in good garden mould, and the result was as follows:

1140 This experiment will furnish matter for much speculation to the attentive reader : but we must proceed. Several other observations on potatoes occur in this volume, all tending to shew that it is a profitable crop; but no other new facts relating to this plant occur.

The Jerusalem Artichoke is a plant of the same genus with the fun-flower. It produces bulbs at the roots, in many respects resembling the potatoe, but it is of a softer confiftence, and more watery. It has been long cultivated in gardens as an esculent, but is not, in general, so much liked as the potatoe, nor has it come into such general use in the field. Mr. Bartley, near Bristol, baving, with some difficulty, procured sets of it, has cultivated it pretty much at large, and thinks it can be done with some degree of profit. He finds it yields about 480 bushels Winchester, per acre, without any dung, and thinks they are about equal in value to potatoes for feeding store pigs; but for fatting hogs they are not so valuable. Their chief recommendations are, he says, the certainty of the crop-that they flourish almost in any foil-do not require any manure, at least for such a crop as the above, and are proof against the severest frosts, &c. He therefore finds it convenient to cultivate fome acres of them annually. The culture is the same as for potatoes.

* This strange 'name may not be familiar to our readers. It denotes, in Ireland, a particular mode of cultivating potatoes; the field is divided into beds, in breadth about four feet, with alleys between, about two feet broad. The sets are planted in the beds, and as they grow, are earthed op with soil taken from the alleys. It was probably the first mode of cultivating this root in Ireland, and it is still practifed in many places. + We presume this should have been lbs.


There is a plant of the convolvulus tribe, which produces bulbs resembling the potatoe. It is cultivated in Spain, and all warm countries, under the name of the sweet potatoe. It would probably be excellent food for cattle, &c, as it grows to a very large fize: We have never heard that any trial has been made how far they would ripen in our climate.

CABBAGES The only extensive trial of cabbages, as a crop, that is recorded in this volume, was made by Mr. Henry Vagg, for which a premium from the society was awarded. They seem to have been cultivated in a masterly manner. One particular that occurs in this experiment deserves notice-The field (12 acres) was divided into two parts; the plants in the first were raised from feeds sown in the month of March, and those on the other division were sown in autumn. The weight of the produce of each was as under: From reeds sown in March

42 tons per acre. From seeds sown in autumn 68

Difference 26 tons per acre. The above crop of 12 acres, Mr. Vagg says, will keep 45 oxen and 60 Theep [Qu. the average weight of each kind of ftock?] for three months.

Turnip rooted CABBAGE. Sir Thomas Beevor continues to cultivate this plant, and thinks he finds great profit in the crop. He advises their being sown on rich and very light land, and as early as the beginning of June. The produce of five acres maintained the following ftock from the 13th of April to the uth of May, being 28. days, viz.

12 Scotch bullocks, weight 40 ftone each,

8 Home bred, two years old. 15 Cows, full fized.


40 Sheep, and i8 horses, fed in the stables, with an allowance of hay.

If the horses be supposed to equal the horned cattle, this would be 53 cattle and 40 sheep 28 days—in all, 1484 days for one ox, and 11 20 days for one sheep. And Mr. Vagg's' 12 acres of cabbages, as above, maintained one ox 4095 days, and one sheep 5460 days; at which race, five acres should maintain one ox 1706 days, and one sheep 2275 days. In this case, if we suppose equal accuracy in both trials, the advantage at first

sight would seem to be in favour of the cabbages—but when the season of the year at which the turnip cabbages come into ale is adverted to, the advantage is clearly on their fide; elpecially when we are told, that 40 hogs were fed by the broken pieces and offals of them for the whole four weeks.

TURNIPS. Concerning this vegetable we have met with little that can be deemed new, or decisive. The only experiment with them is by Mr. Nehemiah Bartley. Four acres of ground, he says, were divided into two equal parts; one half manured with four put-loads (Q. What is the content of a put-load ?] of soapers waste ashes, and the other remained without any manure. Tur. nip seed was sown upon both at the same time. The manured part proved an excellent crop, the other was quite destroyed by the fly. Many observations have convinced us, that few things contribute fo effectually to guard against the ravages of the Ay on turnips, as a plentiful manuring, and early hoeing, which greatly promote the rapid vegetation of the plant at an early period of its growth : and this experiment tends to confirm the fame opinion. Mr. Wimpey, who seems to have bestowed a considerable degree of attention on the culture of this plant, makes a similar remark, p. 141. Several other observations occur in the paper here referred to, that mark the well-informed observer, and deserve the attentive confideration of those who are not well acquainted with the nature of turnips, though nothing will be new to the skilful culoivator.

Mr. Chriftopher Gullet thinks that burning weeds with a thick smoke, in turnip fields, at the season of the fly, will effe&tually prevent the ravages of that insect, but we doubt if that effect would result from the practice proposed. No experiment is here offered to support his theory. The practice of dragging elder-bushes across the turnip field, on which he relies with such an unsuspicious confidence, has been often tried without effect. This correspondent seems to have as yet but little experience in agriculture: time will render him more cautious in his promises of success to those who follow his advice,

CARROTS. We are sorry to find that the culture of this plant seems to be so little attended to by British farmers. Mr. Onley mentions one unsuccessful trial-owing to accidental mismanagementbut he likewise informs us that a crop of from 6 to 700 bushels of carrots per acre [Qu. How are the carrots measured? What is the average weight of a bulei ?] was raised by one of his neighbours, and was employed to fatten oxen with great profit. This is, alas ! almost the only notice taken in this volume of the culture of carrots.


PARSNIPS. Concerning this plant, not a single experiment, or observa. tion founded on actual experience, occurs in this volume but Mr. Hazard, and an anonymous correspondent, from hypothetical reasoning, warmly recommend the culture of parsnips as food for catile. About 30 years paft many attempts were made to introduce the parsnip, generally, as a field crop; but it seems never to have become a favourite with the people. Mr. Hazard advises that the feeds should be sown in autumn, in preference to the spring. Has he himself had experience of this mode of culture, even in the garden? He also advises to transplant them. Few cap-rooted plants succeed by this mode of culture.

ROOT OF SCARCITY. This plant, so warmly recommended to the attention of the British farmer, has not been tried by any of the correspondents of the Bath society except Sir Thomas Beevor, who speaks of it, from an imperfect trial only, in very favourable terms. The feeds, he observes, and plants, are not distinguishable from some kinds of beets, but to try the difference between them, he lowed some beet feed on the same bed at the same time with the feeds of the scarcity plant, and found that the roots of this last, under the fame management, were four times as big, and the leaves of it much larger than the beet. He heard of other plants of the scarcity root that were much larger than his own, which were reared from feeds fown fix weeks earlier in the season. We are glad to find Sir Thomas intends to continue his experiments. We are always diffident of first trials of new plants.

RHUBARB. The observations on rhubarb are less diffuse in the present volume than in the former, and relate more immediately to the business of the farmer.-Dr. Fothergill gives a short account of the method of managing it in Tartary.--Mr. Hayes thinks it may be more speedily propagated by means of flips taken from the root than from seeds. Two other gentlemen give an account, in few words, of the practice they had successfully fol. lowed in propagating and in curing the root for use. Such potices are precisely what is to be wilhed for in such a work as that now before us. .

CORN CROPS. Under this head, we find a continuation of Sir John An, ftruther's experiments of the Drill culture. The result generally is in favour of the grain sown in narrow drills, compared
