carried out with less trouble, or where the trees will produce better fruit or heavier crops. Queensland may well be termed the home of citrus fruits, as we have no less than three native species which are indigenous to the State, and are by no means uncommon in our scrubs. Their presence gives unmistakable proof of the suitability of this State for the culture of fruits of the same family, so that I think a short description of these native species may not be out of place, but will be of some interest to my readers. [Illustration: Young Orange Orchard (6 years old) on scrub land, near Mapleton, Blackall Range. Showing the standing scrub in the background.] _Citrus australis_, the native orange or lime, is both the largest and most common. It grows into a large tree, having a diameter of 15 to 18 inches in the trunk, and a height of 60 feet or more. It produces a quantity of thick-skinned acid fruit, of from 2 to 3 inches in diameter. The skin is full of a resinous sap, and the fruit is of little value. It is a slow-growing tree, though, as just mentioned, it attains a considerable size, is very hardy, and produces a quantity of fruit. Its slow growth, when young, has prevented its use as a stock on which to work improved varieties, but I have no doubt it would make a very hardy stock that would be distinctly disease-resistant. The second variety is _Citrus australasica_, the so-called finger lime, a thorny bush, producing a fruit of from 3/4 to 1 inch in diameter, and 3 to 4 inches long. The fruit has a thin skin, and contains an agreeable acid pulp that varies in colour, in some specimens being of a reddish tinge that resembles the pulp of a blood orange. These two varieties are met with in the Southern part of the State, but the third is a Northern species, to which Mr. F. M. Bailey, our Colonial Botanist, has given the name of _Citrus inodora_, the North Queensland lime. It is met with in the scrubs of the Russell River, and is described by Mr. Bailey as bearing a greater resemblance to the cultivated species than the two former varieties. It produces a fruit over 2 inches long by 1-1/4 inches in diameter, having a thin rind and a juicy pulp of a sharply acid flavour, so that even in its wild state it is a desirable fruit, and takes the place of the cultivated lemon. Where native species flourish as they do here, there is every probability of cultivated species thriving equally well, and this is found to be the case in practice.
