A closely allied and ecjually injurious European species (Tei-ine.'i lucifugus) has also been brought to this country in exchange for ours, but compared with our own species is somewhat rare though already widely distributed. In this country serious damage to buildings from the white ant has not been of com- mon occurrence, especially in the North, except in some notable instances. In Europe our species has caused greater damage, and some years ago gained access to one of the Imperial hothouses at Vienna, and in spite of all efforts to save the building it was ulti- mately necessary to tear it down and replace it with an iron structure. In this country instances are on record of very serious damage to books and papers. An accumulation of books and papers belonging to the State of Illinois was thor- oughly ruined by their attacks. A school library in South Carolina, which had been left closed for the summer, was found on being opened in the autumn to be completely eaten out and rendered valueless. In the Department of Agriculture an accu- mulation of records and documents stored in a vault which was not thoroughly dr}^, and allowed to re- main undisturbed for several years, on examination proved to be thor- oughly mined and ruined by white ants. Humboldt, on the authority of Hagen, accounts for the rarity of old books in New Spain by the frcipiency of the destructive work of these insects. Numerous instances of damage to underpinning of buildings and to timbers are also on record. The flooring of one of the largest sections of the United States National Museum was for some years annually undermined and weakened by a very large colony of these pests which could not be located, and finally the auth
