AiiiGAToK Oil.— A letter from St. Augustine, dated April 12, says.— 

 •• I suDDO..' that you may not liave heard that wo have discovered the utility of alligators. 

 A^ Xator ist^lSnd to be as valuable in his way as a spermaceti whale. An expedition 

 h" lit iWs Place for the river of St. John's, and the dark tributary stream of Black 

 Oeeiwarml^nglith these hideous creatures, with the view of killing them to obtain 

 fhnir o:l The oil of the allifcator is said to be better for lamp, than even whale Ml. and 

 t u ex r'acted from he animal in considerable quantity and without any grea. difficulty. 

 F,^rthi^ discovery wc are indebted to the Indians, who have been in the habit, for how 

 lonVa tin e I know not. of extracting the oil of the alligator and ...10. it for various pur- 

 nose. I make, a fine transparent fluid and burns admirably. Yon know how many of 

 these enomouV'nimals are .hot out of wantonness from fe decks of the .teamboats 

 Jharnlough our waters. 1 expect he-eafter to hear of laws passed for their protection. 

 Every ti^e an alUgator of 18 feet long is shot iu the long grass ot the river banks, or 

 while hl^ss,rimmlng, a barrel or half abarrel of oil, a. the case may be, is wastet^ This 

 Thould nit be We must allow them to be killed only at a proper season when they a^e 

 JaUest and not permit their destruction at the season when they lay iheir eggs. 'Hie 

 Slgator is a formidable looking creature, it is true, but he i. generally harmless. Hi. 

 office is to prowl in the sluggish waters of this southern region, pick up what he can, and 

 S^e!ttinU) excellent oil fir the illumination of our houses. Alligators will l.e hereafter 

 eXemed as u" ful animals as pigs-perhaps more .0. for their keeping costs nothmg. 

 The danger is, thai now that the world has discovered what they are good for, their race

MaiTmoth LocoMOTivEs.-The Great Western have just completed three 

 most Dowerful locomotive engines, built upon the plan and under the superi.itendence of 

 Sr Brunei a sisted by Mr. Gooch. the superintendent of the locomotive riepartmen . 

 I'h^dimen.ons of the Great Western engine ftlie leviathan of locomo ives) are as fol- 

 lows -D°ameter of driving wheel 8 feet ; cylinder. 18 inches : siroke. 24 inches ; boiler 

 between 1." and 16 feet; weight of engine, »6 tons, without water ; weight of the tender, 

 wHhou? ei her coke or water 10 tons ; making a total of 4i; tons. This splendid engine, 

 h, ItTor nassenger trains, drew a train weighing 130 tons up the incline at Wootton Bas- 

 ^ett «°[h as much -.ase and as fast as one of the smaller engines would a passenger train. 

 Th;,r„or„eO?,eeu is likewise for passenger trains, and was built at Swindon: Driving 

 ISee"Tfee?m.metin stroke, fs inches ; cylinder. 16 inches; boiler. 14 feet i weight 

 of engine without water, 26 tons ; weight of temler. it tons, without coke or water. The 

 Sbove^ ng'ines, whc„ their machinery get into perfect order, are intended to be employed 

 Tu propelling the express trains. The other is ;. luggage engine the I remier. having he 

 ^x wEs of 5 feet diameter connected. The dimensions of this locomotive are in other 

 ^sjVcts similar to the Great Western passenger engine. The Premier is d^'ded'y the 

 most Dowerlul employed on the broad gauge, surpassing in itrengtli and speed the Her. 

 "u°es engine"which propelled 406 tons on the experimental trip with the gauge conims- 

 ^loners -An™ and powerful locomotive, the Goliah, was lately tried on the Sheffield. 

 ASn.under.Lyne. and Manchester Railway. It is the largest crank.axle locomotive 

 engine ever built! The cylinders are 18 inche. in diameter, with two feet stroke, mounted 

 on six wheels of four feet six inches in diameter, allcoupled. so that they will not be liable 

 to .npTn wet weather, or with a heavy load, a, is often the case with those constructed 

 ipon the present pr nciple. The engine is calculated to take a load ot up.var,l. of 1,000 

 toM on a level, at the rate of 20 miles an hour. It has given every satisfaction to the 

 company, who have nine more engines of a similar description in progress of building 

 at tho works of Messrs. Sharp, Roberts and Co.

<■ A Working Mechanic."— The improvement of the hydranlic press is 

 yery ingenious, but the small end of the pump piston roust wtjrlk. lo the 

 air • for if it work in a reservoir couiainiug water, the water will be forced 

 through the upper compartmenl into the main cylinder, and consequently 

 the quantity of water pumped in at each stroke will equal the sum and not 

 the difference of the volumes of the two parts of the plunge If our cor- 

 respondent will allow us 10 make the necessary alteration, the descripliOD 

 shall appear next month. If we understand the action of the Arcbimedeao 

 air pump, the mouth of the spir..l tube muit alternately rise above and 

 sink beloW the surface ot the mercury. Hut as the exhaustion advances, 

 the mercury would be elevated, till the mouth of the lube became whoUy 

 submerged.
