Every animal is tied up in feed out every bundle of straw and coarse its place excepting the sheep, and each has fodder, which is in most cases altogether its own portion without fear or molestation. lost, or only used for manure: a plan of this I well know that they consume less food per head by thirty per cent. than they did barn is annexed. during the last winter, when they were fed nearly, if not quite equal to, the ordinary method practised throughout the country. Our oxen, I am satisfied perform more la||bor, the cows yield more milk, and all the animals consume less food by being thus housed and attended. But to the plan of the barn. It is here given.

There are so many collateral subjects connected with the barn and other outbuildings of a farm, that it is hardly possible to give an essay on this subject, without discussing the different methods and economy of feeding stock, with the preparation of the food, preservation of manures, &c. &c. But as the principle of feeding is the same in all kinds of neat cattle and horses, it will apply to all cases. In the first place, I hold that there is no straw, corn, fodder or grass cut on a farm, with the exception, perhaps, of the straw of peas, beans and buckwheat, but what may be consumed as food; therefore all reasonable pains should be taken to secure them in good order, and have them well stored and sheltered for winter food. How many thousand tons of valuable wheat straw have I annually seen in our wheat counties thrown out ftom the threshing mills, and piled up year after year to rot and taint the atmosphere with its offensiveness, when it might all be made into the best of food for cattle, by being housed and chopped with trifling labor! It appears with many farmers to be a matter of no sort of consequence who feeds the stock, or how they are fed, provided they are only fed at all; not considering that there is equal economy in expending the food as in securing it. Look at the season of haying and harvest among our farmers. What preparation for toil and incessant labor, increase of help, high wages, &c. &c. by day-break in the morning, and at work, and no rest till dark. It is the extraordinary season of the farmer, when every thing is sacrificed, even the Sabbath, oftentimes, to toil, and no cessation till it is all

over.

Up

But when the winter comes on, this invaluable food, collected at so much cost and toil, is expended with a heedlessness and prodigality unaccountable to any rational or thinking mind. This, indeed, may seem foreign from the subject of which I am treating, but it is too nearly allied to it to be lost or overlooked.

My own method of feeding is to cut every kind of straw, and even the coarse marsh or meadow hay, in the cutting box, and mix it with a light portion of shorts, bran or oat meal, just enough for the cattle and horses to eat it. In this way they consume every thing. Nothing is lost; for what they leave is taken from the mangers and mixed over again with the new mess. It is the exclusive business of one man to cut the food, clean the stables, and feed the cattle and if he needs assistance, he has it. By this means he becomes acquainted with the appetite and health of each animal, a matter altogether important. If they be out of health, or need extra nursing or attention, he knows it, and provided for them. A change of food is occasionally given, and by this operation all is relished

The barn is framed as if to stand alone, omitting the lower girt at the ends on each side of the large doors. The leantos are then framed on to the barn in the simplest manner-the passage being round the main body of the barn, excepting at the ends, where the passage is in the main barn, and the leantos there only 16 feet wide, and the manger is fitted up to the main barn. Only one passage is made to go into the short stables at the ends. Stalls are made 74 feet wide and broad between, and each ox or cow is tied next to the partition side of the stall, which prevents their getting together, and saves much room. The doors are sufficiently wide to drive in a pair of oxen yoked, and large spikes are driven in the plates all round the stables to hang harness, yokes and chains upon.

The bottoms of the mangers are raised ten inches from the floor, and laid double. The sides of the stable are also battened with thin boards inside, which makes them perfectly tight and warm; windows with sliding shutters are made in the sides, to throw out the manure.

Girts run parallel with the main floor in the posts, across which are laid poles, nine feet above the floor, on which hay or grain can be piled up to the peak.

This barn will hold 200 tons of hay and 46 yoke of oxen, or 100 cows or horses. If only ordinary stock is kept, the long leantos need be only 18 feet wide, and the short ones 14 feet. Granaries can be partitioned off from the bays or stables, as may be convenient. If a threshing machine is used, a part of the stable can accommodate it. Its whole expense, finished complete, is about $1,500.

On this model, barns of any size may be built, and I am well satisfied that, according to the room required, it is altogether the cheapest in cost and simplest in construction of any plan I have seen. If a less proportion of stable room be needed, it may be omitted where convenient. The passages around the ends of the bays and in front of the mangers, are for feeding the cattle, every thing being put in front of them. The passages are wide enough to carry hay, and when the bay is partially fed out, the hay may be thrown directly into the passages.

I would on no account store hay or other material over the cattle, under the stable roofs, although there is considerable room, as I am satisfied from experience, that there is none too much space left for ventilation. The floors are lined with thin refuse

The letting in of fresh air in cold Zacke. and stormy weather, through the sides of the building, gives them colds and disease, to which they are as liable as the human family. But even if only sheds are wanted, I am satisfied that they are better to be attached to the sides of the barn in the way these stables are, than in any other, being more convenient, and allowing the stock to be fed in them with greater economy. The stables attached to this barn being for the accommodation of working cattle mostly, are wider than need be for an ordinary stock, and may be made narrower. But amongst all other plans, I have found none which combine the requisites of cheapness, economy of feeding and storage, like this. It has, withal, an appearance of snugness and comfort about it that greatly embellishes the farm.

If sheds are wanted in addition, they can be attached to the stables and run off in either direction, and accommodated with racks and mangers, as may be required. But every domestic animal on the farm should be fed at the barn, with the exception of sheep, which require, if kept in large numbers, a different and separate course of October last, from a farmer in Bethlehem, I obtained three bucks and nine ewes, in management.

Small moveable barns are frequently built to store it in, and from them fed to cattle during the winter: but this, in the best of weather, is accompanied with waste, particularly in the manure, which is valuable even on the best of soils. It is, besides, much less labor to carry the hay

RAILWAY PHENOMENON.-On Monday last a gentleman of this town, who had taken his place in the hindmost carriage of one of the railway trains from Bolton to Kenyon, witnessed the following singular occurrence :-He was placed with his back to the engine, and had a clear view of the receding line of railway. The train was going down the inclined plane from Baglane to Leigh, at the apparent rate of from 30 to 40 miles per hour. A man who was standing on the side of the railway threw a stone about the size of a hen's egg in a horizontal direction, and with considerable violence, at the train. The stone was distinctly seen by the gentleman in its progress to the carriage in which he was seated, and, having attained its maximum of velocity, it appeared, like Mahomet's coffin, to be suspended in the air for a few seconds, within a foot of the gentleman's head. He seized hold of it, and he describes the sensation which he felt in doing so as somewhat similar to that which would be felt in grasping a stone, in a state of rest, suspended by a thread.-[Bolton Chronicle.]-[This is easily accounted for; both the train and the stone had attained the same velocity.-[Manchester Adv.]

The character of the country through which the road passed, involved every species of excavation; and in the construction of the Railway, almost every mode was successively tried for the purpose of ascertaining the best. While portions of the road were straight, others were of the smallest admissable curvature, and the locomotive power em. ployed had to be such, therefore, as was suitable to both cases. This led to a series of experiments in this department of the Railroad System, which has resulted in the production of Engines preferable to any in use elsewhere-equal in speed to the best imported, and far superior in efficient power. From all these circumstances, the reports of the Baltimore and Ohio Railroad, from its commencement to the present day, have been sought for by Civil Engineers for the sake of the knowledge which they contain, and the frequent demand for them has suggested to the subscriber their republication, with such additional mat ter as shall constitute a Manual of the Railroad Sysin the present state of knowledge on the subject.

Description of the Drawings. Fig. 1 represents a part of the frame of a tender; and

Fig. 2 the ground frame of a coach with 4 wheels, 2 axles, 8 brakes, and 2 slides, all inverted. For the sake of distinction, I will call the large slide [a] the propelling slide, and the small one [6] the adjusting slide. Fig. 3 shows the side view of the two slides. In order that the adjusting slide can be more easily moved, when there is a long train, it can operate over rollers supported from the large slide.

The levers of the brakes meet in the grooves of the propelling slide. Through the end of the levers a pin passes, which is secured to the adjusting slide; there being a groove in the under part of the large slide, so as to admit of a motion of the pins of (say) 4 inches, carrying with them the levers of the brakes.

The propelling slide is coupled to the tender without any play, but the cars must play along the slide (say) 4 inches.

The adjusting slide, being immediately under the other, is coupled to the slide c on the tender, which is to have a shifting motion by means of lever d.

The whole drawing represents the slides properly attached, with the cars pressing forward on the slides, and the two front wheels locked, the cross lever d being secured to its place by an upright hand lever, not shown in the drawing. Now give the engine motion, and both slides will be drawn forward 4 inches, when the checks on the large slide will come in contact with the cross pieces of the cars, which move the cars; by this motion the brakes are thrown from the front wheels, and the other brakes thrown towards the hind wheels, but not against them, and consequently the whole train is ready for running. Now, in order that the engine can run her train back, all that is necessary is to relieve the hand lever on the tender, and give motion to the lever d, by which the adjusting slide is operated upon-carrying with it all the brakes on the cars; by this motion the brakes will be relieved from the foremost wheels, during a retrograde motion, and will not be thrown against the hindmost wheels, inasmuch as it would require the forward motion of the large slide to effect this; suffice it to say, that when the engine is to proceed, lever d must be secured by the hand lever in the position it is now in (as shown in the drawing), and when a retrograde motion is necessary, relieve it and give it a forward motion, which
