several reasons of more than usual in- 

 terest. The path of the shadow passed 

 over accessible regions, in part of which 

 at least the weather conditions were 

 likely to be favorable; stations could 

 be chosen as far apart as Labrador and 

 Egypt ; the period of totality was corn- 



land, Switzerland and Spain. Two of 

 the most elaborate of the expeditions 

 were from this country — that of the 

 Naval Observatory, under Rear Ad- 

 miral Chester, which was carried on a 

 warship to Algeria with very complete 

 equipment, and that from the Lick Ob-

paratively long, and there will be no 

 eclipse for seven years. As is shown 

 in the illustration, the long shadow 

 which the moon casts in space, struck 

 the earth south of Hudson's Bay. The 

 spot of darkness, about 120 miles broad 

 and traveling at the rate of about 

 2,000 miles an hour, passed over Labra- 

 dor and the Atlantic Ocean, and struck 

 the Spanish coast at the Bay of Biscay. 

 It traversed Leon, Burgos and Valencia, 

 the islands of Majorca and Iviza, 

 reached the Algerian coast near 

 Philippeville, thence struck inland 

 across Tunisia, skirted Tripoli, crossed 

 the Nile at Assuan, and finally in 

 Arabia, passed away from the earth 

 into space again. 



Along this line there gathered dur- 

 ing the month of August numerous 

 parties from America (including 

 Canada and Mexico), Great Britain, 

 Fiance, Germany, Russia. Italy, Hol- 



servatory, the expenses of which were 

 paid by Mr. William H. Crocker. The 

 latter consisted of three parties, one in 

 Labrador, one in Spain and one in 

 Egypt, each equipped with a 40-foot 

 photographic telescope, the object be- 

 ing to take similar photographs, to de- 

 termine any change that may occur in 

 the corona in the course of the two and 

 a half hour interval between the ob- 

 servations in Labrador and in Egypt. 

 English observers also had stations in 

 Labrador and Egypt, with similar ob- 

 jects. It appears, unfortunately, that 

 the sky Avas completely clouded in 

 Labrador, and that there were haze and 

 lloating clouds in Spain and the north 

 of Africa, except at Assuan. No 

 definite information in regard to the 

 results of the observations is as yet 

 available. Director Campbell and Pro- 

 fessor Perrine, of the Lick Observatory, 

 in Spain, and Professor Hussey, at
