Of course, he had not gone far when he noticed the brightness of the leaves, and he quickly guessed the cause when he saw the broken jars from which the treasure was still dropping.
Marconi 2 imparted practical utility to this idea by tuning the two circuits together, and the arrangement now employed is as follows: - A suitable condenser C, or battery of Leyden jars, has one coating connected to one spark ball and the other through a coil of one turn with the other spark ball of a discharger S.
In this case a closed condenser circuit is formed with a battery of Leyden jars, an inductance coil and a spark gap, and oscillations are excited in it by discharges created across the spark gap by an induction coil or transformer.
Braun showed that oscillations suitable for the purposes of electric wave creation in wireless telegraphy could be set up in a circuit consisting of a Leyden jar or jars, a spark gap and an inductive circuit, and communicated to an antenna either by inductive or direct coupling (Brit.
Of anchovies alone, to,000,000 jars are prepared annually, while salted fish is, next after bread, the staple food of large masses of the population.
The west side of the palace contained a series of 18 magazines with great store jars and cists and large hoards of clay documents.
Magazines with fine painted store jars came to light beneath the floor of the later " propylaeum."
- Large Oil-Jars In East Magazines (Cnossus).
(a) Domestic, such as vessels of all sorts and in many materials, from huge store-jars down to tiny unguentpots; culinary and other implements; thrones, seats, tables, &c., these all in stone or plastered terra-cotta.
The action of the jars and temper-screw has been described by John F.
Carll as follows: " Suppose the tools to have been just run to the bottom of the well, the jars closed and the cable slack.
The men now take hold of the bull-wheels and draw up the slack until the sinker-bar rises, the ' play ' of the jars allowing it to come up 13 in.
When the jars come together they slack back about 4 in., and the cable is in position to be clamped in the temper-screw.
To telescope the jars for the next blow coming up. A skilful driller never allows his jars to strike on the downstroke, they are only used to jar down when the tools stick on some obstruction in the well before reaching the bottom, and in fishing operations.
As the jar works off, or grows more feeble, by reason of the downward advance of the drill, it is ' tempered ' to the proper strength by letting down the temper-screw to give the jars more play.
The temper-screw forms the connecting link between the walking-beam and cable, and it is ' let out ' gradually to regulate the play of the jars as fast as the drill penetrates.
The " primitive " vessels which have been found in Egypt are small in size and consist of columnar stibium jars, flattened bottles and amphorae, all decorated with zigzag lines, tiny wide-mouthed vases on feet and minute jugs.
The inhabitants grow hemp, Indian corn, coffee, sibucao, cacao, cocoanuts (for copra) and sugar, weave rough fabrics and manufacture tuba (a kind of wine used as a stimulant), clay pots and jars, salt and soap. There is some fishing here.
On the 16th of the month Maimacterion, a long procession, headed by a trumpeter playing a warlike air, set out for the graves; wagons decked with myrtle and garlands of flowers followed, young men (who must be of free birth) carried jars of wine, milk, oil and perfumes; next came the black bull destined for the sacrifice, the rear being brought up by the archon, who wore the purple robe of the general, a naked sword in one hand, in the other an urn.
But although the use of the potters wheel had long been understood, the objects produced were simple utensils tc contain offerings of rice, fruit and fish at the austere ceremonials of the Shinto faith, jars for storing seeds, and vessels for commor domestic use.
It had long been customary in Japan to send students to China for the purpose of studying philosophy and religion, and she now (1223) sent a potter, Kato Shirozaemon, who, on his return, opened a kiln at Seto in the province of Owari, and began to produce little jars for preserving tea and cups for drinking it.
Shirozaemon produced dainty little tea-jars, ewers and other cha-noyu utensils.
Unfortunately, the best experts confined themselves to working for the tea clubs, and consequently produced only insignificant pieces, as tea-jars, cups and little ewers.

In Paris, too, at this time he made a whimsical but pleasant friendship. Marie de Jars de Gournay (1565-1645), one of the most learned ladies of the 16th and 17th centuries, had conceived such a veneration for the author of the Essays that, though a very young girl and connected with many noble families, she travelled to the capital on purpose to make his acquaintance.
It is impermeable to water, and is therefore used in northern countries for roofing, for domestic utensils, for boxes and jars to contain both solid and liquid substances, and for a kind of bark shoes, of which it is estimated 25 millions of pairs are annually worn by the Russian peasantry.
The jars and boxes of birch bark made by Russian peasants are often stamped with very effective patterns.
In prehistoric times in Egypt the dead were laid in the graves on mats in the crouching position common in the burials of primitive peoples, and were supplied with jars of food, flint instruments, &c. Perhaps the attempt was already made to preserve the bodies by drying or otherwise.
The seeds should be kept in sacks or bags in a dry place, and if from plants which are rare, or liable to lose their vitality, they are advantageously packed for transmission to a distance in hermetically sealed bottles or jars filled with earth or moss, without the addition of moisture.
This transfer will take place because the inner coatings of the Leyden jars have greater capacity with respect to the earth than the balls.
Hence the charges of the jars will be increased.
Hence, however small may be the initial charges of the Leyden jars, by a principle of accumulation resembling that of compound interest, they can be increased as above shown to any degree.
In general design and construction, the manner of moving the rotating plate and in the use of the two Leyden jars in connexion with the discharge balls, Voss borrowed his ideas from Holtz.
These combs on opposite sides are connected respectively to the inner coatings of two Leyden jars whose outer coatings are in connexion with one another.
In some cases a failure to understand his meaning led to curious results; for example, the medieval custom, not uncommon in England, of placing rows of earthenware jars under the floor of the stalls in church choirs, appears to have been an attempt to follow out suggestions raised by Vitruvius as to the advantages of placing bronze vases round the auditorium of theatres.
Enormous quantities of wild-fowl of many sorts were taken in clap-nets, to be preserved in jars with salt.
The intestines were removed and placed in four vases (the burial, so-called Canopic jars) in which they were supposed to enjoy the protection of the four sons of Horus, the man-headed Mesti, the ape-headed Hapi, the jackal Duamutef and the falcon Kebhsenuf.
The lower range of jars in the oven had then black tops, while the upper ranges were entirely red.
The early dynastic pottery not only shows the decadent end of the earlier forms, but also new styles, such as grand jars of 2 or 3 ft.
Large ring-stands also were brought in, to support jars, so that the damp surfaces should not touch the dusty ground.
The pyramid times show the great jars reduced to short rough pots, while a variety of forms of bowls are the most usual types (P.R.T..
Drop-shaped jars with spherical bases are typical, and scrabbled patterns of incised lines.
Large jars of light brown pottery were made for storing liquids and grain, with narrow necks which just admit the hand (P.K.).
The native pottery is of a very fine paste, smooth and thin, but poor in forms. Cylindrical cups, and jars with cylindrical necks and no brim, are typical.
The body was brought to the pile in an embroidered robe and jars of unguents and honey were placed beside it.
The contents of the tombs have been nearly destroyed by successive plunderers; enough remained to show that rich jewellery was placed on the mummies, a profusion of vases of hard and valuable stones from the royal table service stood about the body, the store-rooms were filled with great jars of wine, perfumed ointment and other supplies, and tablets of ivory and of ebony were engraved with a record of the yearly annals of the reigns.
In the former method, now commonly known as charging in cascade, the jars are insulated and the outside coating of one jar is connected to the inside coating of the next and so on for a whole series, the inside coating of the first jar and the outside coating of the last jar being the terminals of the condenser.
For charging in parallel a number of jars are collected in a box, and all the outside coatings are connected together metallically and all the inside coatings brought to one common terminal.
The safe voltage for most glass jars is about 20,000 volts for glass 1 ' 0 th in.
In other cases, Leyden jars or condensers take the form of sheets of mica or micanite or ebonite partly coated with tin foil or silver leaf on both sides; or a pile of sheets of alternate tin foil and mica may be built up, the tin foil sheets having lugs projecting out first on one side and then on the other.
In the interior the principal medium of exchange among the natives is the large earthenware jars, imported originally, it is believed, from China, which form the chief wealth both of tribes and individuals.
A hundred or more jars were coupled in series, the cathodes of one to the anodes of the next, and were so arranged that with the aid of side-pipes with leaden connexions and india-rubber joints the electrolyte could, once daily, be made to circulate through them all from the top of one jar to the bottom of the next.
Such ritual use of oil as a o payls or seal may have been suggested in old religions by the practice of keeping wine fresh in jars and amphorae by pouring on a top layer of oil; for the spoiling of wine was attributed to the action of demons of corruption, against whom many ancient formulae of aversion or exorcism still exist.
On the clay stoppers of wine jars of the remote age which goes by the name of the pre-dynastic period, and which preceded the historic period of the first Pharaohs, there are seal impressions which must have been produced from matrices, like those of Babylonia and Assyria, of the cylinder type, the impress of the design having been repeated as the cylinder was rolled along the surface of the moist clay.
His wife had died many years before, and it jars upon us to read how he then commanded the young man to hush his lamentations of sorrow.
They are eagerly drunk by the pilgrims, or when poured over the body are held to give a miraculous refreshment after the fatigues of religious exercise; and the manufacture of bottles or jars for carrying the water to distant countries is quite a trade.
So he called together his merry little fairies, and showing them a number of jars and vases filled with gold and precious stones, told them to carry those carefully to the palace of Santa Claus, and give them to him with the compliments of King Frost.
The fairies promised obedience and soon started on their journey, dragging the great glass jars and vases along, as well as they could, and now and then grumbling a little at having such hard work to do, for they were idle fairies, and liked play better than work.
Of course, he soon noticed the brightness of the leaves, and discovered the cause, too, when he caught sight of the broken jars and vases from which the melted treasure was still dropping.
So he called together the merry little fairies of his household and, showing them the jars and vases containing his treasures, he bade them carry them to the palace of Santa Claus as quickly as they could.
The fairies promised obedience, and were off in a twinkling, dragging the heavy jars and vases along after them as well as they could, now and then grumbling a little at having such a hard task, for they were idle fairies and loved to play better than to work.
King Sun laughed softly to himself when the delicate jars began to melt and break.
Such rich treasures must be kept in a safe place, and so she had imagined them stored in jars and vases in one part of the royal palace.
Jars or of Leyden panes immersed in oil or some form of air condenser, and the inductance coil or primary circuit of the oscillation transformer consists of a few turns of highly insulated wire wound on a frame and immersed in oil.
His transmitter consists of a nearly closed oscillating circuit comprising a condenser or battery of Leyden jars, a spark gap, and the primary coil of an oscillation transformer consisting of one turn of thick wire wound on a wooden frame.
If two Leyden jars L, L were hung upon the conductors which supported the combs, with their outer coatings put in connexion with one another by M, a series of strong spark discharges passed between the discharge balls.
Pottery is made in almost every village, from the small vessels required in cooking to the large jars used for storing grain and occasionally as floats to ferry persons across a swollen stream.
This was a branch of olive or laurel, bound with purple or white wool, round which were hung various fruits of the season, pastries, and small jars of honey, oil and wine.
Franklin in 1747 and 1748 made numerous investigations on the Leyden jar, and devised a method of charging jars in series as well as in parallel.
