The proprietor of this manufactory is an accomplished and amiable nobleman ; his experiment in this case has been highly successful.

One great evil is the impossibility hitherto experienced of keeping the roots any length of time, which makes it expedient they should be worked as soon as possible after they are taken from the ground.

BIRCH'S FIRST-CLASS RAILWAY-CARRIAGE.

BIRCA'S FIRST-CLASS RAILWAY-CARRIAGE.

Sir,- In the month of November, 1835, the London and Birmingham and Great Western Railway Company put forth a proposal inviting engineers, and others, to a professional competition in designs for first-class carriages, ubich was liberally backed by the promised premiuins of 100 and 2001.

As one (and probably one of the humblest) of the competitors, I essayed my skill, and designed what I considered to be a carriage meeting the views of the Company ; I was, however, one of the unsuccessful candidates. Thinking, nevertheless, that some of the arrangements may not be altogether deficient in originality or utility, I solicit its insertion in your widely-circulated work. The following is a copy of the directions given to the competitors: –

" London and Birmingham and Great

Western Railways. « First-Class Carriage. “ To be capable of accommodating at least twelve passengers.

A convenient arrangement for a greater number is very desirable, and will be preserred if it should not involve other objections.

May be placed on four or more wheels; if on six, the interval between the most distant axles, not to exceed ten feet.

“ To rest on springs.

• Particular attention to be directed to the elastic mode of connecting one carriage with another; as also the various expedients which are already employed to prevent the jerking action of the carriage when the train is put in movement, and to the shocks which are generally experienced when the velocity of a train is lessened, or when it is brought to a state of rest.

“ It is considered desirable to reduce, as far as practicable, the height of the body of the carriage from the ground, so that it be not less than twelve or fourteen inches above the level of the rail.

" The extreme width of any portion of the body of the carriage not to exceed seven feet.

“ In furnishing the above particulars, the Directors are to be understood as simply stating what appears to them to be desirable with reference to the present state of railway experience in the construction of carriages for passengers. Plans, therefore, which may not be in strict accordance with these data will receive the most mature consideration, according to the advantages they may severally appear tu possess.”

The following are the few observations I addressed to the Directors :

mitting for your approval a de.

sign for a first-class carriage, I have adhered as nearly as possible to the printed instructions, and beg to offer a few observations by way of explanation.

« The body is in three divisions, one double and two single. The double division is intended to carry eight persons, and each of the single ones four, which, with the two conductors' seats, allows room for eighteen passengers. The depth of and (in the former) the space between the seats is considerably more than those afforded by ordinary stage-coach conveyances, and the consequent ease and comfort of the passengers are thereby insured.

The carriage having both ends alike, will not require turning on the rails; and may be drawn or propelled without altering the position of the passengers. The extreme length of it is fourteen feet; the width, six feet six inches; the height from the rail to door is two feet two inches; and the whole height is seven feet.

" It will be observed, that the springs at. tached to the connecting rods at each end of the carriage are different, and must be a mat. ter of choice or experience. That marked A acting upon cranks will throw the pressure of the springs outwards, and will consequently prevent, or considerably lessen, the concussion and jerking action upon the train being put in motion or stopped.

• The one marked B acting with slidingrods, drawing from a long spring, and buffing against a .double nut-cracker, will hare a similar effect.

“ From the axles cranks are attached to the springs, and pressing outwards will allow the wheels to rise in the slots, and surmount any obstruction of five or six inches without throwing the body out of its equilibrium.

“ I presume that a tender will be attached to the train for the conveyance of luggage; but if it is deemed indispensable, an imperial, and rods may be attached to the top, for the carrying of the same. There is room for stowage under each of the seats. " I remain, Gentlemen, with respect, " Your most obedient servant,

" EUGENIUS BIRCH. “ Feb 1, 1836."

NEW SYSTEM OF GEOLOGY.
