About three miles beyond Cana, we passed the village of Turan. Near to this place they Turan. pretend to shew the field where the Disciples of Jesus Christ plucked the ears of corn upon the Sabbath-day? The Italian Catholics have named it the field “ degli Setti Spini ;” and they gather the bearded wheat, which is annually growing there, as a part of the collection of relics to be conveyed to their own country. The heat of this day was greater than any to which we had yet been exposed in the Levant ; nor did we afterwards encounter anything so powerful. Captain Culverhouse had the misfortune to break his umbrella -- a frivolous event in milder latitudes, but here of so much importance, that all hopes of continuing our journey depended upon its being repaired. Fortunately beneath some rocks, over which we were then passing, there were caverns“, Caverns. excavated by primæval shepherds, as a shelter

and actually of dressing meat’: into these caves we crept, not only for the purpose of restoring the umbrella, but also to profit by the opportunity thus offered of unpacking our ther. mometers, and of ascertaining the temperature of the atmosphere. It was now twelve o'clock. The mercury, in a subterraneous recess, perfectly shaded, the scale being placed so as not to touch the rock, remained at one hundred degrees of Fahrenheit. As to making any observation in the sun's rays, it was impossible ; no one of the party had courage to wait with the thermometer a single instant in such a situation.
Basaltic Pheno-. mepa.
Along this route, particularly between Cana and Turan, we observed basaltic phænomena. The extremities of columns, prismatically formed, penetrated the surface of the soil, so as to ren
der our journey rough and unpleasant. These Origin ex- marks of regular or of irregular crystallization, plained.
generally denote the vicinity of a bed of water lying beneath their level. The traveller, passing

series of successive plains, resembling, CHAP. in their gradation, the order of a staircase, observes as he descends to the inferior stratum upon which the water rests, that where rocks are disclosed, the appearance of crystallization has taken place; and then the prismatic configuration is vulgarly denominated basaltic. When this series of depressed surfaces occurs very frequently, and the prismatic form is very evident, the Swedes, from the resemblance such rocks have to an artificial flight of steps, call them Trap; a word signifying, in their language, a staircase. In this state Science remains at present, concerning an appearance in Nature which exhibits nothing more than the common process of crystallization, upon a larger scale than has hitherto excited attention. Nothing is more

It was in consequence of a journey upon the Rhine, in the year 1793, that the author first applied the theory of crystallization towards explaining the formation of what are vulgarly called basaltic pillars; an appearance common to a variety of different mineral substances, imbedded in which are found Ammo nites, vegetable impressions, fossil wood, crystals of feldspar, masses of chalcedony, zeolite, and sparry carbonate of lime. He has seen the prismatic configuration, to which the term basaltic is usually applied, in common compact limestone. Werner, according to Professor Jameson, (Syst. of Min. vol. I. p. 372), confines basalt to “ the floetz Trap formation," and (p. 369, ibid.) to the concretionary structure ;

Edin. 1804,) in stating the geographical situation of basalt; a vague term, as he properly expresses it, which ought to be banished from mineralogy: it is in fact applied to any substance which exhibits the phænomena of crystallization upon a large scale, whenever the prisms are large enough to be considered as columns.
