The stick contains some irregular galleries measuring from 

 2^ to 3>^ cm., approximately, in diameter, in some places more 

 or less honeycombed, while they widen out in others into a sort 

 of a chamber more or less irregular in shape, the one chamber in 

 the stick being in the region of a knot which has been hollowed 

 out. Small side galleries occur, one measuring 13 by 6 mm.; 

 another, smaller, is 10 by 5 mm.; while a third is 8 by 20 mm. 

 These galleries mostly run with the grain. The side of the 

 largest gallery is 7 cm. in width, the other side being detached. 

 Opposite the chamber this gallery widens to yj^ cm. The por- 

 tion of the chamber contained in the stick is 7^ cm. one way, 

 by from i^ to 3 cm. the other. Another gallery is 6 by 2 >4 cm.; 

 another, 6 by i>^ cm. The galleries are more or less lined with 

 the frass from the termites. Then there are pockets: One, 2>^ 

 by i^ cm. in diameter, and 5 cm. deep; another, 2>^ by \% cm., 

 and 3>^ cm. deep. Other pockets are smaller. 



It is asserted by the foreman on the place from which these 

 termites came, that they are frequently found in the live wood. 

 A row of large cotton woods along an acequia showed an unhealthy 

 condition, and was cut down. Most of these were found to be 

 mined by the termites. They seemed to prefer the more moist 

 parts of the trees, either live wood or wood moistened by the 

 proximity of the water in the acequia. 



NATIVE HABITS OF SEQUOIA GIGANTEA. 



BY GUSTAV EISEN. 



One of the most beautiful of all trees, as well as one of the 

 very largest, is our well-known Sequoia gigantea, or the Cali- 

 fornia Big Tree. No tree known is so well adapted to be a 

 " memorial " tree as this giant of the California Sierra Nevada, 

 not alone on account of its size, which reaches 350 feet in height 

 by 45 feet in diameter, nor by its beautiful and symmetrical 

 form, in which it is not surpassed by any other coniferous tree, 

 not even the famous cedars of Lebanon, Himalaya, and Atlas. 

 But the chief advantage of the Sequoia for memorial planting is
