scales attached to a common axis, each scale bearing a seed. The seed ripens 

 in October and blows away leaving the empty spikes erect on the tree. 



Although a handsome shade tree, the tulip is rather hard to grow suc- 

 cessfully. It has the fleshy roots of the magnolias which makes it hard to 

 transplant. In transplanting care should be taken not to bruise the roots, or 

 allow them to dry out. The trees should be planted in the early spring in deep, 

 rich soil. Careful attention is needed for several years, but after the tree be- 

 comes established it grows rapidly and is little troubled with insects. Because 

 of the size it attains at maturity, it should not be used on narrow streets. 



UMBRELLA TREE 



The umbrella tree (Melia azedarach var umbraculiformis) is widely planted 

 in California because of its rapid growth and its quickness in giving shade. 

 Its common name is given because of the umbrella-like shape of the tree. It 

 is also called the China tree due to its Asiatic origin. 



The umbrella tree is popular because of its delicate bright green foliage, 

 which it carries until late in the season, and its long sprays of fragrant lilac- 

 colored blossoms. When well grown it forms handsome specimens, but in 

 many cases it is not properly pruned with the result that too many branches 

 are formed and breakage from the wind results. This tree also has objection- 

 able features due to the excessive litter of leaves and its slippery fruits which 

 are apt to cause accidents The umbrella tree has its place, but its faults 

 do not recommend it for widespread planting as a street or highway tree in 

 view of the many more desirable species that can be used. 



WALNUTS 



The original home of the walnut was probably in the north of Persia. 

 The Greeks thought highly of the tree and accounted for its excellence by a 

 story that Bacchus loved Carya, a king's daughter. Her sisters were jealous 

 and interfered, and Bacchus, greatly enraged, changed them into stones, and 

 Carya into a walnut. 



Introduced into Italy before the Christian era the walnut was named 

 Juglans, a corruption of Jovis glans, the nut of Jove, food nut for the gods. 

 It was looked upon as sacred to Diana, whose festivals were held beneath its
