128 ON CERTAIN RECENT CHANGES IN THE CRATER OF STROMBOL1. 
Kicco ascended the mountain and observed a succession of eruptions. 
Four considerable ones, besides smaller ones, took place from bocca No. 
5, some moderate ones from No. 4, while Nos. 2 and 3 discharged masses 
of smoke. 
1899. Stromboli was mostly in its usual condition, with occasional 
increases of activity. There was a slight increase of activity at the 
beginning of February. On March 6 a very violent explosion occurred 
in one of the side craters, followed by the formation of two small 
cones in its floor, and on the following days increased activity con¬ 
tinued. During this year Prof. Matteucci stayed nine days on 
Stromboli, and made six ascents. The eruptions all took place from a 
little eccentric cone on the southern slope of a large crater of explosion, 
probably 4, 4 bis, or 5, and there were six other bocche, but they only 
emitted smoke. The mountain was again active in November, and 
about the 10th of that month a new bocca, No. 6, opened on the Sciara 
below and to the north-east of No. 5. 
1900. Stromboli was unusually active from March to November, 
especially in October. Many of the explosions were sufficiently powerful 
to shake the whole island and cover it with dust. The chief explosions 
were from bocche 4, 4 bis, and 5, all situated towards the western part of 
the Sciara. The later observations are not yet published, but Signor 
Liberator Castalan, syndic of Filicudi, whose house commands a full 
view of Stromboli, informed me that there was a severe eruption of 
Stromboli in December, 1903, and January, 1904, also others five and ten 
years previously. Between those times nothing special occurred, but 
the mountain was never absolutely quiet. 
Signor Guiseppe Eenda, Postmaster of Stromboli, also spoke of an 
eruption in November and December, 1903, during which a stream of 
lava ran down the Sciara from about December 10 to 20, and a new 
bocca formed on the north-eastern part of the eruptive area near the 
Torrione (Torrella ?). 
There was an earthquake in February, 1904. 
1904. I stayed four days on the island, and ascended the cone on 
April 20 and 22. The photographs were taken April 20. 
On May 30, 1904, Signor D. Yasalo, Capo Posto del Semaphoro di 
Stromboli,* made an ascent of the mountain, and, the craters being quiet, 
was able to ascend the eastern Faraglioni (Torrella), from whence he 
had a near view of the “ Apparato Eruttivo.” He found in the part 
which I have called the fumarolic area a new bocca, which he calls No. 7. 
It is about 20 metres east-south-east from bocca 2, and about 6 metres 
by 4 metres in extent. It was in a state of the weakest activity, and 
emitted whitish smoke, apparently being in a similar condition to that 
on April 20, when I photographed the locality, as shown in Plate IY.
