Some discussion occurred on grape soils, but we gather nothing of value from the report except the following, by Prof. J. P. Kirtland:

"Alluding first briefly to the Lake Shore climate, he proceeded to the subject of soils. No perfect analysis of soil from Kelley's Island and to Erie Co., N. Y., had ever been made. The shales of these localities, and the clays, came once from what is now the bed of Lake Erie, scooped out, Agassiz says, during the glacial period. On the soil thus formed the grapes are now grown. The analysis of Prof. Emmons of the wood and bark of grapes was read, and the speaker said that according to Prof. Lie big's theory, no vegetable growth could be had on soil in which any element found in the vegetable was absent. Grapes, therefore, could not be grown on any soil which did not possess all the elements found in the vine by Professor Emmons. The soil about Cincinnati had enough lime and potash to sustain grapevines for a few years; but after some years' cultivation the vines began to show signs of starvation. Then mildew or some other disease attacked the half-starved vines. On new land, the healthy vines might have resisted the attack. There are places - some of them in this vicinity - where the grapevines will last after we are dead and gone. There are others where a few years will see the vines growing sickly and unprofitably, and dying.

The soil about Cleveland contained plenty of lime - he had found a bed of plaster of Paris on his own farm. Every 100 lbs. of the shale of the Lake Shore contains from 7 to 15 lbs. of potash in the mica, which forms about half of the shale. Chloride of soda was found in the old deer licks all along the Lake Shore. Sulphur plays an important part in the nourishment of the grape, and it is found here in great quantities - so much that it is now contemplated in this city to get sulphur from the shale of the Lake Shore, instead of importing it, for making sulphuric acid. In answer to ah inquiry, Prof. Kirtland said, to manure sandy grape land, put on a dressing of about two inches of broken shale. At Kelley's Island and Sandusky, when the three or four feet of shales are exhausted, they must supply the loss somehow. But from the mouth of Huron River, Erie County, O., east to below North East, Pa., there is an exhaustless bed of shale. Grape-growing in this region must be permanent. At Kelley's Island there is no certainty of permanent grape raising.

From Cleveland to Avon Point he knew every inch of ground, and take that strip a mile wide from the lake, you will find it the richest in the organic elements for grape culture to be found this side of New Mexico and California. The strip may be four or five miles wide from the lake in some places, but it would be too far from the lake to get the influence of the water. There is but one soil - the clay soil - for grapes.
