a few miles north of the center line of the path. Logroño and Zaragoza are a few miles within the northern edge of the shadow, and La Coruña and Valladolid are a few miles within its southern edge. Valencia appears to be located almost exactly on the southern edge. Excellent maps of the eclipse path, on both large and small scales, prepared by the Madrid Observatory and published by the Spanish Government, were very useful to observers in deciding upon their observing stations. Director IÑIGUEZ, of the Madrid Observatory, kindly placed at the disposal of observers a considerable quantity of meteorological data, notably the observations for 1897 and 1898, in order that they might judge of the weather probabilities. The best promise for a large number of clear days, small rainfall, low humidity, and small diurnal range of temperature seemed to be afforded by the region south and southwest of Zaragoza. Burgos, with slightly poorer weather conditions, as shown by the records, was to be the destination of numerous expeditions, as well as the objective point of the tourists, good and sufficient reasons for our avoidance of it. A consideration of all the conditions, several months before leaving Mt. Hamilton, led to the decision that the expedition should locate in the Almazan-Ateca-Daroca region.

The scientific apparatus and supplies for the three expeditions were packed on the first three days of June for shipment by wagon to San Jose, thence by railway to Galveston and Gulf steamer to New York.

Mr. and Mrs. CAMPBELL, Mr. and Mrs. PERRINE, and Volunteer Observer THOMAS E. MCKINNEY, Professor of Mathematics and Astronomy in Marietta College, Ohio, sailed f om New York on July 6th, per White Star steamer "Romanic,” bound for the Azores, Gibraltar, Naples, and Genoa. The freight for the Spanish and Egyptian expeditions was on the same ship. The passage was an especially favorable one, as there was neither wind nor wave until the day before reaching Gibraltar. Nevertheless, the steamer's schedule was not maintained. The arrival at Gibraltar was a day late, which caused only minor inconveniences; but the delay in reaching Genoa was more serious in its consequences.

Mr. and Mrs. CAMPBELL disembarked at Gibraltar and journeyed overland to make necessary official arrangements

at Madrid, to select and prepare the site for the observing station, and to provide living accommodations. They stopped a day at Granada to see the Alhambra and other historical and architectural interests of this city, but, with eclipse duties ahead of them, they were in no mood for sightseeing. The other members of the expedition continued on the same ship, first to Naples, where Professor HUSSEY received in person the Egyptian freight, and thence to Genoa, where transfer to a steamer sailing direct to Barcelona was to be made. Unfortunately the belated arrival at Genoa vitiated the arrangements kindly made by the American Consul for a quick transfer to the Barcelona steamer, for which there should have been abundant time. This failure to make connections involved a delay of one week at Genoa, a loss that could ill be afforded at the observing station. Passage was secured on the steamer "Jativa," leaving Genoa on July 27th and reaching Barcelona on Saturday evening, July 29th.

The freight having been seen on board a railway car, Mr. and Mrs. PERRINE proceeded to the eclipse station, arriving on August 2d. Dr. MCKINNEY traveled on the train which carried the instruments, keeping watch on the eclipse car to guard against delays. He brought the car to its destination on the morning of August 3d.

The main line of railway from Madrid to Zaragoza crossed the central line of the shadow-belt at the village of Alhama, in Aragon. This place is justly famous for its wonderful springs of warm water. Its baths were known to and patronized by the Romans in the days of the Roman occupation, and they continue to be used extensively in the late summer months by the Spaniards, for rheumatic and other complaints.

Interviews in Madrid with Professor CASARES, Astronomer IÑIGUEZ, and others led to the provisional selection of Alhama for the observing station. The weather indications seemed to be as promising there as anywhere along the line; no other expedition was planning to locate in Alhama; it was the point of easiest access for the imported instruments and for daily supplies, as well as for the assistants who were to come from Madrid, Zaragoza, and northern Europe; and there was a hotel with which arrangements for accommodations could be made. The latter point was of considerable importance, as

there were to be about twenty-five members of the expedition during eclipse week; and while food supplies in abundance had been taken from New York, in case it was necessary to establish our own camp, we were soon convinced that this should be avoided at almost any cost.

Mr. and Mrs. CAMPBELL reached Alhama on July 21st. This village of fifteen hundred people has an interesting location from the geological point of view. It is in a valley bounded for the most part by steep and conspicuously stratified walls of rock from two hundred to four hundred feet high. Near the center of the village these walls approach each other quite closely, so that the form of the town is roughly that of an hour-glass, whose length lies southwest and northeast. The fertile floor of the valley is subject to severe floods, and could not be thought of in connection with a site for observations. After careful search of the surrounding country, a satisfactory location was found near the southernmost part of the village, on a small hill rising about sixty feet above the valley. Some forty years ago a palacio real had been built, an artificial lake constructed, and the surrounding grounds improved to supply accommodations for the King, who was coming to take the baths. The hill referred to is in the palace grounds. It is fairly well covered with pine trees. especially on the slopes lying below the lines of sight of the instruments at the time of the eclipse. It is easy of access and, equally important, easily closed to inquisitive visitors. It was therefore definitely decided, on July 24th, to locate here. A half-dozen large rooms in a thick-walled masonry house, perfectly adapted to mechanical and photographic work, were found near the foot of the hill. Satisfactory arrangements were made with Hotel Los Termas for the accommodation of the party. During the following nine days, while waiting for the other members of the expedition to arrive with the instruments, laborers were employed in repairing the road to the summit, making the excavations, constructing the brick piers, and providing for the water and other supplies.

These preliminaries having been arranged, the assembling, mounting, adjusting, and testing of the instruments proceeded rapidly from the date of their arrival. We were fortunate in having the assistance of Dr. MCKINNEY and Dr. R. S. DUGAN,
