Leader. _i\ Tew Guinea is a perfect undeveloped mine oi wealth. Irrespective of its naturalresouces of soil and climate for the yield of tropical productions, it pos sesses great and varied mineral riches amongst which are gold, pearls, and the rarest precious stones, such as sapphires and rubies, several specimens of which were obtained by Captain Moresby, 1,.X, when he visited and explored a portion of its coasts a few years ago in the Basilisk. It is to this enterprising officer that we owe most of the know ledge that we posses of tfew Guinea, and his description of the country presents us with a most attractive picture. The inhabitants are described as an inoffen sive race of people, ready to engage in trading operations mth strangers, and showing a disposition to appreciate the advantages ot civilisation. The country is mountainous, and thus affords every variety oi climate, aud the means of the most divcrsihed productions of the soil lue lcity ranges slope down gradually to the sea and afbord facilities for what Ilumboldt describes as the peculiar char acteristic oi the cultivation of similar regions m tropical South 'America. On the low lands at the foot of the moun tains would flourish plantations of cotton, rice, coftee, the sugar-cane/ nutmegs, cinnamon, cloves,, and spices of ail kind Higher up, the vine, the orange, the olive, and the fig would, find their priate climate; whilst at a more elected range, gram of all-kinds, and other pro ducts ot the cool districts of Europe would grow in luxuriance. The forests contain ebony, sandalwood, and mariy kinds of dyewoods. In a word, the natural resources of the country are rich in the highest degree, and almost limit less. \et this most f clicitious region of the globe, which is lying at our very doors, has, up to the present at least, with the most preverse remissness -oh our part, been allowed to go a-be«nne tor an owner. This folly has now, we trust, come to an end; and as the' British (xovernmenc appears to need some encouragement from this quarter to make a move in the direction of an nexation, every Administration and Legislature in the whole Australian group must at once formally com municate the express desire' of 'the colonial public to have ]N Tew Guinea brought under the British flag without delay.
