832 . (Concluded from page 821.) But it is not at all necessary for the usefulness of the suspension railway, that it should be in every respect as capable of enduring heavy loads as the ‘railway now most usually constructed. The important question is, whether, taking into consideration the expense of its construction, the cost of transportation upon it will be less than upon an ordinary road. If this point is es- -tablished as it has been, beyond all doubt, its im- portance is manifest. There are many parts of the United States where the increase of popu- lation and of business calls for greater facilities of communication; yet the travel is not sum- cient to support the enormous expense of_ the double iron railway. There are other sections so rugged and uneven, that whatever might be the amount of travel, it could not pay the ex- pense of embankments, excavations, and other works necessary for attaining the level required for the road. In all such cases the suspension road, on account of its comparatively trifling expense, can be used to great advantage. The average cost of a suspension railroad, built with prudence and economy, extending over a coun- try, the surface of which presents no peculiar advantages or disadvantages, is about one quar- ter of that of the double track iron road now in use, and this diflerence is increased in propor. tion as the country, over which the road is to be constructedlis more rugged and uneven than usual. Now suppose that the suspension road is only capable of bearing one third of the mo- mentum which the other road can bear, (and this is certainly la greater allowance than it would be necessary to make in practice,) yet the cost being one fourth that of the other, and its power onethird, it follows, of course, that the suspension road would be niuch,_the most economical. , In a new country, therefore, where means are limited, it must be of immense advantage. Its merits have not hitherto been generally known. It has been but very little used in England, pro- bably on account of the high price of timber, and on this side of the Atlantic we have been slow- to adopt suggestions that have not been proved ' and tested by experiment. But it is now get- ting into more extensive. favor in those partsof the country where timber is abundant. It Will, no doubt, in a. short time, prove a most impor- iant method of inland transportation. B3‘ We owe an apology to our friends, for not is- suing these numbers on Saturday, as promised. They have been delayed two days longer, in order that the Index and Title Page might accompany them, to make the work complete for the year. December 30, ‘I833. .

M. J. YOUNG L... ‘v~. F! If Mathematical Instrument Maker, No. 9 Dlick street, Philadelphia. The following recommendations are. respectfully submitted to Engineers, Surveyors, and others interesied.. Baltimore-, 1832. In reply to thy inquiries respecting the instruments manu- factored by thee, now in use on the Baltimore and Ohio Rail- road. I cheerfully furnish thee wiili the following information. I‘he whole number of Levels now in possession of the depart- ment ofconstruction oftliy make is seven. The whole num- ber ofthe “Improved Compass” is eight. These are all ox- clusivc ofthe number in the service of the Engineer mid Gra- duation Department. Both Level and Compasses are in good repair. They hay: in fact needed but little 1‘-epnirs, except from accidents to which all lllBl.l‘lllIlBn[£l ofthe kind are liable. I have found that thy patterns for the levels and compasses have been preferred by my assistants generally, to any others in use, and the Improved Compass is superior to any other de- cription of Goniomeler that we have yet tried in laying the rails on this Road. This instrument, more recently improved with a reversing telescope, in place of the vane sights, leaves the engineer scarcely any thing to desire in the formation or convenience of the Compass. It is indeed the most couipleielv adapted to later al angles ofany simple and cheap instrument that I have yet seen, and I cannot but believe it will be preferred to all other; now in U26 for laying ofrailn—-and in fact, when known, Ithink itwill be as highly appreciated for common surveying. Respect ully my friend, ' JAMES P. STABLER. Sulperlntendant of Construction 0 Baltimore and Ohio Rltilroad. Plillndel hie, February, i833. Having for the last two yea.l'u mate constant use of Mr. Young's “ Patent Improved Compass,” I can safely say I be lieve it to be much superior to any other instrument ofthe klnd, now in use, and as such most clieerf'ull_v recommend it to En. sincere and Surveyors. 1:). H, GILL, Civil Engineer. Germantown. February, 1833. For a year past I have used lustruinents made by Mr. W. J.

I consider these lnatru ments admirably calculated for layin out Railroads, and can recommend then: to the notice of'1'.‘ngl nears us pi'e1'er.able to any others for that purpose. , HENRY R.6AMPBELL.
