"Very well," said Dick, giving him some papers, and then indicated two different rows of the small concrete blocks. "These marked A were made from cement in our store; the lot B from some I took from Oliva's stock on the mole. They were subjected to the same compressive, shearing, and absorbent tests, and you'll see that there's very little difference in the results.

The following formulæ will give all the stresses in the bowstring girder, without the necessity of any diagrams, or basing any calculations on the assumed action of any of the members of the girders: These results show that the method generally adopted in the construction of bowstring girders is erroneous; and one consequence of the method is the observed looseness and rattling of the long embraced ties referred to at the commencement of the article during the passage of the live load; the fact being that they have at such times to sustain a compressive stress, which slightly buckles them, and sets them vibrating when they recover their original position.

Resuming then the action afresh, without dislodging, or giving me the trouble of parting from my sweet tenant, we played over again the same opera, with the same harmony and concert: our ardours, like our love, knew no remission; and all the tide serving my lover, lavish of his stores, and pleasure-milked, he over-flowed me once more from the fulness of his oval reservoirs of the genial emulsion: whilst, on my side, a convulsive grasp, in the instant of my giving down the liquid contribution, rendered me sweetly subservient at once to the increase of joy, and to its effusions: moving me so, as to make me exert all those springs of the compressive exsuction, with which the sensitive mechanism of that part thirstily draws and drains the nipple of Love; with much such an instinctive eagerness and attachment, as to compare great with less, kind nature engages infants at the breasts, by the pleasure they find in the motion of their little mouths and cheeks, to extract the milky stream prepared for their nourishment.

In columns, even as long as forty diameters, steel of 90,000 pounds tenacity will exceed the mildest steel 35 per cent., or iron 50 per cent., in compressive resistance. The present uncertainty consists largely as to how high-tension steel will endure the manipulation usual with iron without injury.

I had now totally taken in love's true arrow from the point up to the feather, in that part, where making no new wound, the lips or the original one of nature, which had owed its first breathing to this dear instrument, clung, as if sensible of gratitude, in eager suction round it, whilst all its inwards embraced it tenderly, with a warmth of gust, a compressive energy, that gave it, in its way, the heartiest welcome in nature; every fibre there gathering tight round it, and straining ambitiously to come in for its share of the blissful touch.

From the veins the blood is, for the most part, returned to the heart by the compressive action of the muscles, the constant change of posture and by the respiration acting both as a force and suction pump. All of these factors are at their maximum during bodily activity and at their minimum during rest.

Then only will its gravitative force be sufficient to cause incoming matter to fall upon it with so powerful an impact as to produce intense heat. Further, the compressive force of a small planet will be a less effective heat-producing agency than in the case of a larger one.

However it may be compressed, air returns, on liberation, to its original volume, and while thus perfectly elastic it is also the most compressible of bodies. This elasticity arises from the repulsive force of its particles, and is always equal to the compressive force which it balances. A glass vessel full of air, placed under a receiver and then exhausted by the air-pump, will burst into atoms.

In addition to horse lore, John Porter was a fair judge of human nature, and, beyond doubt, there was a streak of velvet in Alan which would have twisted easily in the compressive grip of the race course. The Porter family were not the only dwellers of Brookfield who took part in racing.

The windows are made of optical glass similar to that used in the largest telescopes. They are nearly as thick as the hull and have a compressive resistance almost equal to that of armor steel. Although so thick, they are crystal clear, and a speck of dust on the outer surface is easily seen.
