The average declination of the needle throughout this district I found to be 1 degree east, the result of many amplitudes and azimuths; there is, however, in the vicinity of many of the volcanic hills great local attraction.
Of the climate I can only say that during the five months we remained on the coast we never experienced the same inconvenience from it that we frequently have done within the limits of the settled districts of the colony; the weather was, however, principally fine, and the sky clear during our stay, only two showers having occurred—one at the latter end of May and the other in June. The meteorological register kept at Nickol Bay shows the following results, from observations taken at all hours of the day and night:—
Column 1: Month in which
thermometer reading was recorded.
Column 2: Maximum.
Column 3: Minimum.
May : 80 : 65.
June : 76 : 63.
July : 78 : 56.
August : 80 : 54.
September : 83 : 65.
October : 92 : 70.
Under the peculiar circumstance of the thermometer being placed on a sandbank in the sun during the hot days in October, it rose to 178 degrees of Fahrenheit, whilst the lowest it ever fell to was up in the hills, in July, when it was 2 degrees below freezing just before sunrise.
The winds continued to blow almost uninterruptedly from the east and south-east during the first four months, veering to the south-south-east and south and occasionally to the north-east. Latterly the wind was alternately south-east in the morning, and north-west or westerly in the afternoon; the sky becoming frequently overcast, and every appearance of the near approach of the rainy season, which it has been observed by navigators and explorers to do about the beginning of November, and continue to March.
Amongst the natural productions I would first briefly refer to the beds of the pearl oysters, as they are likely to become of immediate commercial importance, considerable numbers having been gathered by the crew of the Dolphin at their leisure time, the aggregate value of which, I am told, is between 500 and 600 pounds; besides pearls, one of which has been valued by competent persons at 25 pounds. The limits of the bed are as yet undefined, but there is good reason to believe, from the position of it, that with proper apparatus ships could soon be loaded with them.
Sandalwood was found in small quantities, very highly scented, but too widely scattered to become of much importance as an article of export.
Of indigenous fruits, etc., we observed the adansonia, or gouty-stemmed tree of Sir G. Grey (nearly allied to the baobab or monkey bread-fruit of Southern Africa), sweet and water melons similar to those formerly seen by me on the Lyons River, but of much larger size; a small gourd; a wild fig, well-tasted; and a sweet plum, very palatable, were found in tolerable abundance.
