For the purpose of marmalade making the Poor- 

 roan orange is grown to a limited extent. 



CITRUS STOCK. 



Another thing the planter will have to consider, 

 and that is upon what stock the young trees are 

 budded. In Australia citrus trees are usually budded 

 upon Seville, sweet orange, and lemon stock. Of 

 the three the Seville stock makes the hardiest tree, 

 and American and Australian experience seems to 

 be at one in this matter. The Seville is not so liable 

 to collar rot as the lemon and sweet ora.nge, and can, 

 therefore, be grown on wetter land than either of the 

 other two, and has proved itself able to withstand 

 floodings and to grow in fairly moist situations. 

 The Seville as a stock causes slow growth to the 

 variety budded upon it, makes for a rather bushy 

 tree, and the fruit, although of good quality, is 

 somewhat smaller than that grown either upon 

 sweet orange or lemon stock. 



SWEET ORANGE STOCK. 



The sweet orange as a stock makes for a quick 

 growing, vigorous tree. On a good, loose, loamy 

 soil, where water does not stagnate around 

 the butts of the trees, and where the drainage 

 is good, the sweet orange stock gives good 

 results. It gives a large and vigorous tree, and 

 induces a good crop of good-sized fruit. Owing 

 to a widely spread belief that the sweet orange 

 is more resistant to the effects of moisture and to 

 the baneful influences of many of the alkalies dis- 

 solved by irrigation water, many growers prefer it 

 as a stock to the rough lemon. 



ROUGH LEMON STOCK. 



As a stock, the lemon has the reputation of being 

 the least hardy of the three varieties under considera- 

 tion, and is usually held to be more liable to collar
