Page 303 - It follows: 1, talc; 2, gypsum; 3, calcite; 4, fluorite; 5, apatite; 6, orthoclase; 7, quartz; 8, topaz; 9, corundum; 10, diamond.
Page 31 - When reckoned in per cent., the error would be such a small fraction of 1 per cent. as not to be worthy of attention. The specific gravity was determined by dividing the average of the two dry weights by the difference between the average dry weight and the weight of the cube suspended in water.
Page 302 - The feldspar group contains two series of minerals, under both of which are included several species and sub-species. Certain of the species differ in the elements which enter into their composition, while others differ merely in the percentage of such elements. The two series of minerals are known by the name of their most common member, as orthoclase and plagioclase. Orthoclase is composed of an admixture of potassium, aluminum, silicon, and oxygen, with occasionally a small percentage of sodium...
Page 27 - valuable in determining the effect of combining masonry and metal; Df joining different kinds of masonry or of joining new masonry to old ; in calculating the effect of loading a masonry arch ; in proportioning abutments and piers of railroad bridges subject to shock, etc.
Page 302 - The hardness is 3. Calcite is sometimes clear and transparent, but is more often white or cloudy. It sometimes contains impurities which impart a brown or pink color. It has a perfect cleavage in three directions, by means of which it breaks into small six-sided pieces, with inclined faces, called rhombohedrons. Calcite is often mistaken by the inexperienced for quartz. The color of the two minerals is almost identical, but if one will bear in mind that the hardness of calcite is 3 and that of quartz...
Page 306 - The olivine group is now more correctly known as the chrysolite group. The different species differ somewhat in composition, being composed of varying proportions of magnesium, calcium, iron, and manganese, in combination with silicon and oxygen. The hardness ranges from 6 to 7. The predominant color is what is commonly known as olive green. The luster is vitreous. Olivine is a constituent, mainly, of the more basic igneous rocks, such as diabase and gabbro. It alters very extensively to chlorite,...
Page 31 - The method of obtaining the porosity ordinarily employed is as follows : The sample to be tested is heated at a temperature of 100° C. to drive off the moisture. After cooling, the sample is weighed, and then slowly immersed in distilled water. After bubbles cease to be given off the sample is removed from the water, and the surfaces quickly dried with bibulous paper, after which the specimen is again weighed. The difference in weight gives the increase due to the absorption of 1 Iowa Building Stone,...

It is true that long rows of brownstone buildings are not very enlivening, but since all buildings generally approach this color after a few years, without respect to their original color, this has little weight as an argument against the use of brownstone. The only consideration in the selection of stone to be used in the business portions of a large city, ought to be one of strength and durability. In the residence portions of a city, where beauty is one of...
Page 17 - ... lowers, the water freezes, and upon the melting of the ice the crack will be found to have widened. Repeat the process and the crack will open still wider. If the process is continued the two walls of the rock will finally be shoved so far apart that the water is no longer retained. The ice acts as a wedge which automatically adjusts itself to the size of the crack, until the opening is sufficiently wide and deep to allow the free passage of the water. Alternate freezing and thawing of the included...
Page 17 - Chemical and geological essays," says : "Other things being equal, it may properly be said that the value of a stone for building purposes is inversely as its porosity or absorbing power.
