seen by the column, How many failed. No. 13, called "Grand Rubellum," by the Professor, or the red Lammas wheat, I believe, out of 58 grains lost 14; whereas No. 5, the Coturianum, lost none. No. 1, a variety suspected to be delicate, but one of the best wheats, both for produce and meal, from 64 grains, only lost 3. In this manner I was led to judge of the hardiness of the varieties, and I was well pleased to observe that the white, or most valuable sorts, were full as hardy as the red.

It appeared that out of seven hundred and fiftyfour grains, the whole number sown singly, seventyfour never came up; a loss of nearly one tenth, even with the care and attention I bestowed on them.

I have further discovered, that some sorts are still more delicate, of very precarious and uncertain habits.

The habit of growth of many varieties, differs very considerably; some being of a close upright growth, others spreading and trailing along the ground; some tillering sooner than others: those in the experiment had all done so by the middle of March. On the 27th, they were hoed for the second and last time, and were afterwards perfectly free from weeds.

I was not, at that early period of my research, so attentive to the moment of flowering as I have since been; as the knowledge of that precise moment might prove of the greatest importance to an intelligent farmer, there being an interval of a week, or

ten days, in the period of flowering of some of the sorts. Hence, a judicious selection, with due care as to the time of sowing the variety, that will soonest come into flower, would enable him, not only to keep his crops from intercrossing by the intermixture of their farina, but as they would ripen in succession, enable him also to bring in his crops in rotation, as each variety ripens, without being hurried by his whole crop being fit for harvesting at the same moment, which is now too often the case.

It may be noticed that a single grain, picked up on the high road by chance, which I immediately perceived to be of an entirely different form, and of a larger size, than any I had yet seen, though sown a week later than the others, was the first to ripen, and was cut on the 31st of July. It has still preserved its early habit, which I know, having now a small field of it.

No. 9, the latest, was only ripe on the 8th of August. This difference in the period of flowering and ripening, could further be increased by arrangement, as to exposition and soil.

The next and chief object of attention, was their comparative produce in grain.

No. 1, produced 3lbs. 3oz. from 61 grains, and 3 lbs. 9oz. weight of straw, of a beautiful white colour: whereas No. 14, a red variety, only produced from 59 grains, 1lb. 10 oz. of wheat, and 2lb, 5 oz. of

straw. Here then was an immense advantage in favour of No. 1, which produced nearly double the quantity of wheat, and a third more straw-its average of tillers being ten, whereas that of the inferior sort was only six; and Professor La Gasca, it must be recollected, imagined that this last, was one of the most productive varieties, evincing the positive necessity of comparative experiments, to ascertain the relative produce of wheat, which the theory alone, even of the learned Professor himself, could never have discovered; he merely having judged, from the external appearance of the wheat, its squareness, and compact form; than which, nothing could have proved more deceptive.

No. 8, a downy variety, was still more productive than No. 1, as fifty-five grains produced 4lbs. 4oz. of wheat, and 3lbs. 13 oz. of straw, its average of tillers being 11: the straw of a fine colour, and the sample very beautiful, though scarcely so fine, or thin-skinned as No. 1. This produced nearly three times as much corn as No. 14, and a third more straw.

These comparisons decided me to attempt the future cultivation of those, I had discovered to be the most productive, by a comparison of the produce of a whole ear. From a further examination, as to the relative produce of 23 grains, of every sort, taking Nos. 5 and 7, which had but that number of grains in an ear, and by thus drawing two scales of comparison, I hoped that a satisfactory conclusion might be

arrived at. Hence, the minimum, scale or number, was fixed on to compare their relative produce, from an equal number of grains. Thus, No. 7, containing twenty-three, the least number of grains in one ear, became the standard, to compare the relative produce of the whole fourteen sorts.

By following up these comparisons, it was suspected that Nos. 5, 7, 3 and 1, were among the hardiest varieties; but here their merits in some degree cease; No. 8 being the most productive, and Nos. 1 and 6 being equal. No. 8 is also the second most productive in straw, the fourth in the average number of tillers, also the second in weight of grain, and the third in produce of flour. It was therefore believed to unite many good properties, and has proved to be a highly productive, and valuable variety, of a downy or hoary sort, with a roundish white grain, rather thin-skinned, producing very fine flour, which makes delicious white bread. It has produced fifty-one bushels to the acre. No. 1, being an ear of a fine variety of wheat from Dantzic, has also proved to be highly valuable, though the straw is so tall, that it might be apt to lay, in moist situations.

I was induced also to cultivate No. 5, being a seedling variety, not at all disposed to sport or change, producing a very fine round white sample: it has proved very productive. It produced from 23 grains more than any, but then it had the advantage of double
