Seite 89 - December immediately preceding the application for a bill by which any lands or houses are intended to be taken, or an extension of the time granted by any former Act for that purpose is sought...
Seite 75 - That the broad gauge involves the greater outlay, and that we have not been able to discover, either in the maintenance of way, in the cost of locomotive power, or in the other annual expenses, any adequate reduction to compensate for the additional first cost.
Seite 57 - ... same rendered less soluble, so that the otherwise soluble alkaline parts of the manure may not be washed away from the other ingredients by the rain falling on the land, and thus separating the same therefrom. And it is the combining carbonate of soda or carbonate of potash, or both with carbonate of lime, and also the combining carbonate of potash and soda with phosphate of lime, in such manner as to diminish the solubility of the alkaline salts to be used as ingredients for manure (suitable...
Seite 58 - Both preparations are ground to powder; other salts or ingredients in the state of powder are added to these preparations and mixed together, or those not of a volatile consistency may be added when the preparations are in a state of fusion, so that the manure may represent as nearly as possible the composition of the ashes of the preceding crop. This is assuming that the land is in a high state of cultivation, but if it be desired to grow a particular crop on land not in a high state of cultivation,...
Seite 79 - ... these experiments demonstrate beyond any doubt that the greater portion of the material should be distributed on the upper side of the beam. We have arrived therefore at a fact having a most important bearing upon the construction of the tube ; viz. that rigidity and strength are best obtained by throwing the greatest thickness of material into the upper side. Another instructive lesson which the experiments have disclosed is, that the rectangular tube is by far the strongest, and that the circular...
Seite 58 - Preparation of manure for land which has had a wheat crop grown on and removed therefrom. — Take of the first preparation six parts by weight, and of the second preparation one part, and mix with them two parts of gypsum — one part of calcined bones — silicate of potash, (containing six parts of silica) — and one part of phosphate of magnesia and ammonia. And such manure is also applicable to be used after growing barley, oats, and plants of a similar character.
Seite 10 - ... shall be laid on the table of the House, and be printed and delivered one clear day before the second reading. 9. That such railway bills as shall have been read a first time before the House, shall agree to these resolutions, shall be read a second time within seven clear days thereafter. 10. That such of the Standing Orders as relate to the composition of the committees on private bills, and the orders consequent thereon, be suspended so far as regards railway bills pending in the course of...
Seite 57 - Now, the object of this invention is to prepare manure in such manner as to restore to the land the mineral elements taken away by the crop which has been grown on and removed from the land, and in such manner, that the character of the alkaline matters used may be changed, and the same rendered less soluble, so that the otherwise soluble alkaline parts of the manure may not be washed away from the other ingredients by the rain falling on the land, and thus separating the same therefrom.
Seite 175 - ... reaction must be equal. Therefore, I do not believe that it is the steam that causes the irregular action, but I believe it to be the mere weight of the pistons themselves, and therefore if we could contrive to balance the pistons by the weight upon the wheel, we should get rid of that very much...
Seite 169 - Mr. Barlow came to the conclusion, that the strength of a bar should be double that of the mean strain, or load. In his first report, he thought from 10 to 20 per cent, would be sufficient; that is, for a 12-ton engine, as the weight is at present distributed, a strength of 7 tons would be ample provision ; and with greater accuracy of construction, a less strength would suffice ; or rather, allowing the same strength, an engine of 14 or 16 tons might be passed over with greater confidence. Thus,...
