year. As a matter of fact, it rather tends to afford contrast with our ever- 

 greens, making us realize all the more the wealth of possibilities that our 

 state affords for the growth of different types of flora. 



In connection with this word on deciduous trees, I should like to mention 

 among others the native sycamore (Platanus racemosa), one of the most 

 picturesque features of our landscapes, both in winter and summer. This 

 hardy tree, admirably adapted to stand the rigors of our climate, should 

 make a good street tree, though I do not remember having ever seen it so 

 planted. Another tree which all Southerners love and which Professor 

 Charles F. Baker of the University of the Philippines strongly advocates, is 

 the tulip tree (Liriodcndron tulipifera) , said to be well suited to avenue 

 planting. One of its characteristic features is the abundance of beautiful

 thrives well in California, where it fruits to perfection. These trees are all 

 beautiful, hardy, popularly liked : why not plant them on some of our avenues 1 

 Among our commonest and, I think, most beautiful street trees is the 

 pepper tree {Schimis molle) which receives much censure and fault finding 

 from the multitudes. It is true that it harbors scale in an infected district 

 where it is neglected and starved; but so do our fruit trees. If, however, a 

 pepper is given occasional water and kept in a healthy growing condition it 

 is found to be remarkably free from insect pests, reducing this tendency to 

 the minimum. It is trtie, also, that the pepper berries produce annoying 

 litter at certain seasons of the year, l)ut their beauty would more than atone 

 for a considerable inconvenience during this short time. Besides, the com- 

 bination of the rugged, twisted trunk and feathery, drooping foliage is hard
