Among the numerous watering places in Virginia, our attention has been drawn to that which is named at the head of this notice, by several individuals who tested its virtues during the last season, and who speak highly of the situation and management of the Springs, and the efficacy of its waters. The mineral qualities of these Springs have been long known, and they have been resorted to for some years by persons living in their vicinity. But the character and circumstances of the original proprietor, a descendant of the early Dutch settlers of the country, prevented their improvement until within the last year or two. He had a full sense of the mineral treasure which enhanced the value of his property, and refused all offers from those who wished to purchase the site of the Springs; while he had not the means of bringing them into profitable use, by erecting buildings for the accommodation of visiters. Many individuals were, nevertheless, in the habit of drinking the waters of the Springs during the warm season, and of sojourning for a few days in the rude and imperfect dwellings which he had erected: and with the moderate income thus obtained from this mine of natural wealth, its sturdy proprietor seemed well satisfied. At his death, his successors disposed of the Springs and the adjacent lands to the present proprietors; and buildings were erected last year, on a limited scale, with every regard to the comfort of the traveller and the invalid. The consequences of a more liberal arrangement were immediately felt. The number of visiters last season exceeded the means of accommodation; and the managers have in the interim, made the most active exertions to meet the growing popularity of their establishment, having completed additional apartments, which will enable them to provide for the comfort of one hundred persons. The scenery in the vicinity of the Springs has been described to us in glowing colors, as combining every variety of the magnificent and the beautiful—and we have also been assured that the fare and attendance are worthy of all praise; so that we feel safe in recommending the enlarged establishment of the proprietors (Messrs. Dibrell and Watkins,) to the attention of travellers for health or pleasure.

Dagger's Springs are situated within easy distances from some of the most interesting towns in the Valley of Virginia—they are forty-five miles from the White Sulphur; twenty-two from Lexington; eighteen from Fincastle, and sixteen from Pattonsburg. The following letter from a distinguished physician, affords all necessary information as to the medicinal properties of the waters, and the management of the establishment:

Danville, April 28, 1835.

I visited Dagger's Spring on the 24th of last July, and on the next day proceeded to subject the water to a number of chemical tests. The experiments performed, though not as full and as satisfactory as I could have wished, were sufficient to demonstrate that the water possesses highly valuable properties, and sufficient also to make us somewhat acquainted with the nature of those properties. The most active mineral ingredients in the water are carbonated alkalies. In this it differs materially from the White and Salt Sulphur, and is more nearly assimilated in its qualities to the Red and Gray Sulphur. It is however more decidedly alkaline than either of those Springs. This peculiarity will ever recommend it to persons subject to acidities of the stomach, and to the other concomitants of dyspepsia; while the large quantity of hydrogen that it contains, will render it useful in all of those complaints for which sulphur water is usually prescribed.

The following experiment was performed with the view of ascertaining the quantity of gas contained in the water. Three measures of the water were placed in a retort, and the bulb of the retort plunged in water, heated to the temperature of 108 Fahrenheit. The gas, as it was extricated, was received over mercury, in a graduated measure. The result was, that the three measures of water yielded one measure of gas. This gas was subsequently tested, and found to consist of sulphuretted hydrogen, azote, and atmospheric air—principally of the former.

The presence of iron is not detected by the usual tests; but the water, when treated with prussiate of potash, and subsequently with sulphuric acid, yields a blue precipitate, which is evidently prussiate of iron—the sulphuric acid having a stronger affinity for potash than the prussic acid, disengages the latter. The acid thus disengaged, unites with the iron in the water, and forms the prussiate of iron or prussian blue.

Although the water contains but about 36 grs. of mineral substances to the gallon,1 it acts, under certain circumstances, with great promptness. It effects upon the system are invigorating: it promotes digestion and improves the secretions generally; it strengthens without producing an undue excitement, and may therefore be used beneficially in some cases, in which the water of the White Sulphur, from its stimulating properties, would prove destructive.

1 The smaller of two springs at the Red Sulphur contains about 60 grs. per gal. The larger, which is most used, does not contain but about 24 grs. per gal.

I will only say in conclusion, that I was pleased with the manner in which the establishment appeared to be conducted, with the spirit of enterprise manifested, and the taste displayed in the plan of improvement, which was kindly exhibited to me. I met with no situation among the mountains susceptible of as great improvement as that selected for the buildings. It may be made a second Eden.

I am engaged in preparing a work for the press, in which this Spring will be more particularly noticed, and attention directed to objects of interest in the surrounding country. It would have been completed before this, but for the peculiarities of my situation, which allow me but little leisure for literary pursuits.
