THE KEDWOOD. 



" The quartermaster's lumber yard had piled for some four or five months a quan- 

 tit}' of Eedwood, which upon my departure in October was still free from ants. 



"John ]MacLeod, of Manila, has a room in one of his houses finished in Redwood, 

 constructed over fifteen years ago, and to this day three-fourths of the original 

 amount remains still in good condition, one-fourth having been worn out and replaced 

 by other lumber. " 



Reference iy made in Bulletin No. 33 of the Bureau of Forestr}^ 

 (p. 20) to certain experiments conducted in Manila, P. I., by Mr. 

 D. N. McChesney, as reported by Capt. George P.' Ahern, Chief of 

 the Philippine Forestry' Bureau, in which it would appear that Red- 

 wood, Incense Cedar, and Western Hemlock were not attacked, while 

 Douglas Spruce, Bull Pine, and Engelmann Spruce were seriously 

 injured.
