green shades. Many of these markings are very distinct and readily seen from a distance. The shades of green vary from light to very dark. The appearance of this marble is different in different pieces. In some the white largely predominates, while in other pieces the green overshades the white.

As an example of this marble, attention may be called to some of the interior paneling of the Albany Commercial Bank. Here there are panels made up of four pieces, so that a lozenge-shaped figure occupies a large part of the center. Some of the panels are 18 feet high and 13 feet wide and are extremely elegant. In the exhibition room of the New York City Library there are twenty-five columns of this variety. Also the interior of the elegant building of the American Trust and Securities Building, Chicago.

Dorset White.-Seen from a short distance this marble appears pure white and only as it is more closely examined are the numerous, but delicate, light brown or smoky bands and veins distinguished. This is one of the Dorset marbles which are quite easily distinguished from those of the Rutland district. They are harder, more coarsely and therefore more brilliantly crystalline and unsurpassed as building marbles. The great New York Public Library on Fifth Avenue is built of this marble. This and the preceding are quarried at Dorset by the Norcross-West Marble Company.

Dove Blue Rutland.-This is one of the most quiet and delicately shaded of the Vermont marbles. It is a bluish drab, usually varying less in shade in the ground color than most marbles, though not wholly without shading in some pieces. Mingled with the bluish or grayish ground, which gives tone to the stone, there are numerous and often elongated small white spots, the whole broken by more or less distinct dark veins, giving an exceedingly agreeable effect. Quarried at West Rutland by the Vermont Marble Company. The fossils shown in Plate V are in this marble.

Florence. This marble is used both for monuments and building. The bluish white ground is clouded and veined with dark shades, varying from smoky to black. In some specimens the darkest shades are not conspicuous, but form rather an undertone. Others are more distinctly shaded and darker. Quarried at Fowler by the Rutland-Florence Marble Company. Gray Building. This is rather dark for one of the light varieties. Its general tone is a bluish gray, slightly mottled with white and veined with dark shades. The veins are usually quite fine. Quarried at West Rutland by the Vermont Marble Company.

Italio. This is another of the marbles which resemble the more common varieties of imported Italian. It is a moderately light marble. The ground is bluish white, over which there are much darker bluish cloudings and shading, as if in a semi-fluid mass of lighter shade a considerable amount of darker material had been mixed. There are also not very distinct, very sinuous dark lines. Quarried at the Columbian quarry, Proctor. Until recently by the Columbian Marble Company, now by the Vermont Marble Company. Light Cloud Rutland. This is, as would be inferred from the name, much like Best Light Cloud, but it is a different trade variety. In this the green veins are more distinct and on this account the general tone is somewhat darker. However, the difference between the two is not great. Quarried at West Rutland by the Vermont Marble Company.

Light Columbian Building.-This is another of the very light marbles. Like several of these lightest varieties, it appears white on hammered or sawed surfaces, the marking what there may be, becoming manifest only when the stone is polished. When this variety is finished in this way, indistinct blotches and irregular bluish veins appear. Indeed, usually, there is a decided though faint bluish tone over the whole, so that the stone is never pure white. Quarried at the Columbian quarry, Proctor, by the Columbian Marble Company, formerly, now leased by Vermont Marble Company. Light Florence. This is also like some of the light Italian marbles. The ground is not a clear white, but has a bluish cast. It is thickly clouded and blotched by elongated dark spots and also by distinct lines. The markings are more regular than those of many of these marbles and often form somewhat uneven, but plainly seen, bands or lines across or lengthwise the piece as it is sawed across or along the block. Quarried at Fowler by the Rutland-Florence Marble Company.

Nat

Light Green Cloud. This is one of the Dorset marbles. The ground is a very clear, sparkling white. Through this there are scattered little clouds or patches of a greenish shade. Some are quite dark and are therefore distinct, others are lighter and so indistinct that they appear more like shadows than areas of any color. urally these shaded areas vary greatly in different pieces. In some the dark spaces cover more of the surface than the light, while elsewhere the light predominates. It is a good building marble, but is used especially in interiors. The Slater Building, Worcester, Mass.,

is finished in some parts of its interior with this marble. at Dorset by the Norcross-West Marble Company.

Quarried

Light Sutherland Falls.—This is a light, but not one of the lightest marbles. Through a nearly pure white ground there are distributed numerous, quite distinct, dark bluish veins. In most specimens the light ground greatly predominates over the darker veining. In occasional samples the veins are greenish rather than bluish. This variety is quite variable in shade in different layers, some being very much darker than others. It is harder than most of the Rutland marbles. Quarried at Proctor by the Vermont Marble Company.

Listavena. This is a peculiar marble in that the usual irregularity or sinuosity of the veining or banding is here replaced by what in effect is quite a regular arrangement of the colors. The general colors are green and white in wide bands or lines which extend across the slab, or block, often in fairly straight fashion. Or it inay be that we have not so much regularly straight veins of green as those that, because they all trend in the same direction, appear to be more regular than they really are. These green or greenish lines or bands are not usually as extensive as is the light ground which is itself in bands between them, though in some samples the whole surface is shaded in greens. This variety in some respects is like the Brocadillo, but in the latter the green colors occupy more of the stone than in the Listavena. The Brocadillo is more clouded and the Listavena more banded in its coloration. The latter is generally lighter than the other. Quarried at West Rutland by the Vermont

Marble Company.

Mountain White.—In the region of Danby and Dorset there seems to have been a somewhat different sort of metamorphism by which harder and more brilliantly crystalline marble was formed from the original sedimentary rocks. The crystals-all true marble has a crystalline structure—are larger and thus larger reflecting surfaces appear in the smoothed surface of the stone. For these reasons all these marbles are exceptionally good building stones. The Mountain White is, as would be expected from the name, a very light stone, sometimes pure white, sometimes veined with light, or darker, brownish coloring. Much of this marble has recently been used in the new Senate office building in Washington, including sixty large columns. Quarried at Danby by the Vermont Marble Company.

Pittsford Italian.-This may be used for interior work, but it is chiefly used as a building stone. It is a very light stone, though not
