Page 93 - By a Portland cement is meant the product obtained from the heating or calcining up to incipient fusion of intimate mixtures, either natural or artificial, of argillaceous with calcareous substances, the calcined product to contain at least 1.7 times as much of lime, by weight, as of the materials which give the lime its hydraulic properties, and to be finely pulverized after said calcination, and thereafter additions or substitutions for the purpose only of regulating certain properties of technical...

To attempt, however, to train young men separately for the position of foremen would be under the existing organization of labor an impossibility.

Of the seed sown a relatively small percentage develops plants, and probably there is no crop in which failure to secure a satisfactory stand of plants is more common.

Page 473 - ... perfection in the adaptation of means to ends, than is required to meet the merely economic standard. So far as the demands of beauty can be distinguished from those of economy, the kind of beauty most to be sought in the planning of cities is that which results from seizing instinctively, with a keen and sensitive appreciation, the limitless opportunities which present themselves in the course of the most rigorously practical solution of any problem, for a choice between decisions of substantially...
