es patents for power-brakes up to the close of 1872 numbered 59. In England, from 1840 to 1866, there were patented 22 electric brakes; from 1835 to 1865, 20 hydrostatic brakes; from 1838 to 1866, 30 pneumatic brakes; from 1836 to 1866, 54 steam-brakes. Since 1869, seven companies for the manufacture of power-brakes which lies over the Bristol and Exeter and Great Western Railways. Leaving Exeter at 10.30 it is timed to reach Paddington at 2.45; including a stoppage of five minutes at Bristol, and the inevitable and vexatious ten minutes at Swindon, the journey of 194 miles occupies 4 1/4 hours. The speed of 70 miles an hour sometimes attained upon railways is equivalent to about 35 yards per second. At this rate have been organized in the United States, and more than one sixth of the 444 railroads in this country and Canada are now provided with them. The principle, in all cases, consists in releasing, by means of devices at the hand of the engineer, a power stored up in

fall, as the tide ebbs and flows. 4. The axle of the wheel may be fixed, the wheel receiving the influx and efflux of the water, being more or less submerged according to the state of the tide. The former is the preferable arrangement. See also tide-wheel. Tide-wheel. A wheel turned by the ebb and flow of the tide, and employed as a motor for driving machinery, etc. The most remarkable variations in the tide are at Chepstow, where the rise of spring tides is about 60 feet; at Bristol it is 40 feet: in Mount St. Michael's Bay it is 46 feet; in the Bay of Fundy and on the coast of Nova Scotia it is about 60 feet; whilst in the Northern Atlantic it is on the average from 10 to 12 feet; at St. Helena only 3 feet; and on the shores of the islands of the Pacific it is barely perceptible Where the rise is so extreme, it is produced by the contraction of the sides of the river or estuary, as the Bristol Channel, for instance, or a convergence to one point of wide stretches o

4 for the 8 ribs. Weighing the ribs, to give them all an equal flexure, requires 8 more transfers from hand to hand, and threading the ribs to the stretchers brings up the total series of operations required for the frame to nearly 150. Within comparatively few years, this cost, in London, from 1/2 d. to 2 1/2 d. each, for common umbrellas and parasols; one man and four boys can put together 100 frames daily. For covering each frame, women received from 1 d. upward. A tradesman in Bristol, England, has just made a monster umbrella for an African chief. It is 65 feet in circumference, the lancewood ribs being 6 feet long, and there are 140 yards of material in it. It is covered with red, blue, and white chintz, and takes two men to expand it. In Trinidad are colonies of ants, known as parasol ants, from the fact that each individual carries a leaf in his mouth, which shades his back. These luxurious insects, on being disturbed, rush into their holes and bring out a lot

nd out of Liverpool in 1860 was 48,317; equal to 132 per day. The docks of Liverpool are inclosed spaces taken from the river Mersey, the area afterward dug out. The London docks are excavated in the land on both sides of the river. The Bristol docks are made by walls and locks, which arrest the water of the river Avon, a new cut being made for the river, and for the passage of vessels up and down. See list under dock.

The differential windlass is shown in Carpenter's Mechanical philosophy, London, 1844, page 282. It is therein credited to Mr. Moore of Bristol. The hand portion of the continuous rope passes over the larger wheel, and the weight portion over the smaller wheel, the value in hoisting power being equal to the difference in the radii of the two wheels. It is the same principle as shown i

his arms, he would exclaim, This is nothing but the hand of God. He taught his soldiers to regard themselves as the instruments of God's glory and their country's good. In the great revival which prevailed in England under the preaching of Whitefield, the Wesleys, and their associates, godly soldiers bore a conspicuous part. And in America, no lay preacher was more zealous and successful than Captain Thomas Webb, of the British army. Converted under the preaching of John Wesley at Bristol, England, he soon began to recommend in public the grace which had renewed his own heart. Afterwards in America he preached with great fervor, and as he always appeared before the people in his military dress, he attracted large crowds, and many of his hearers felt the power of the gospel proclaimed by this soldier of the Cross. The name of Col. Gardiner is like ointment poured forth. Wild and profligate in early life, he strove, after his conversion, to make some amends for his sinful care

are accusations to which I briefly reply. Now that we are all united in the policy of Emancipation, they become of little consequence; for even if I was once alone, I am no longer so. With me are the loyal multitudes of the North, now arrayed by the side of the President, where, indeed, I have ever been. If you will bear with me yet longer in allusions which I make with reluctance, I would quote, as my unanswerable defence, the words of Edmund Burke, when addressing his constituents at Bristol. And now, gentlemen, on this serious day, when I come, as it were, to make up my account with you, let me take to myself some degree of honest pride on the nature of the charges that are against me. I do not here stand before you accused of venality, or of neglect of duty. It is not said that, in the long period of my service, I have in a single instance sacrificed the slightest of your interests to my ambition or to my fortune.

The light of the fire must have been seen a great distance. At midnight, by the advice of friends, I left the city with a friend in a carriage, and rode to Bristol, a distance of twenty miles, where I took the steamboat next morning for home. From the Needles's, whose mob-threatened home he quitted, on the night of the burning of the hall, with the parting benediction, Peace be with you, Mr. Garrison took refuge, by invitation, at the friendly house of Morris L. Hallowell, No. 240 North Sixth St., where the Junior Anti-Slavery Society had gathered to meet Henry C. Wright. About two o'clock the next morning (May 18) a covered carriage was driven

Yet I trust he will soon see his way clear to speak out in our behalf. Perhaps I may conclude to return home in the Great Western, which is to sail from Bristol on the 25th July. If not, I shall aim to take the steamer Acadia, for Boston via Halifax, 4th August. I am waiting, with all a husband's and a parent's anxiety, to hear from you. May the intelligence prove pleasurable to my soul! Dearest, I am Your loving husband. London retained its hold on Mr. Garrison for another fortnight.
