just outside the tree guard, an earthenware pipe, 6 inches in diameter. This 

 ■can be done at pLinting time, and a cover fitting on the top of the pipe 

 does away with any liability of accident. If filled with water occasionally 

 during the summer UKjnths. the bottom of the hole will be kept moist, and 

 the roots of the tree encouraged to strike downwards. Light surface 

 watering has just the opposite effect. In the snvered streets of the city and 

 suburbs of Melbourne, the trees are sufi'ering from want of water, some of 

 them are gradually dying, and unless artificially watered, will not survive 

 many years longer. 



What to Plant. 

 We are here again indebted to the men of the " old brigade " for 

 many useful object lessons scattered about our towns. It mav be laid down 

 as a broad general rule that deciduous trees are more suitable for street- 

 planting than those which retain their foliage all the year round. In 

 the winter months, we want sunshine, not shade, and in atldition the 

 autumn leaves add a new tone to Australian landscapes, while we mav 

 *' rejoice and be glad '" when the breath of spring brings again to our 

 view the tender cff'^n '^f bud and folincre. 



I. ORIENTAL PLANES. L\ 1 ILETUN .MRLi:i. C ASl LEAIAINL. 



In Melbourne, Bendigo, Castlemaine, and other districts enjoying a 

 temperate climate, the Oriental Plane {Plataniis orientalis) makes an ideal 

 street tree. (See illustration, Xo. i, of I>yttelton-street, Castlemaine). 

 The Castlemaine streets were planted in the years 1872-3 by Mr. P. Doran, 

 curator of the local Botanical Gardens. Mr. Doran still holds this impor- 

 tant position which he has adorned for .so many years. The Planes were 

 put in 60 feet apart, with a Bluegum {Eucalyptus globulus) in between 

 each of them. The gums eventually became diseased, and were removed 

 some years ago. Many of the planes are now 50 feet high. The one 

 at the right hand corner of the photograph is 50 feet high, has a head 

 diameter through branches of 60 feet, and a trunk girth at 3 feet from
