There Are Also-RansAmong Pole Woods Besides the above-named woods there is an extensivelist of also-ran, a few of which are very good, buttoo rare for any but very local use. Others are usedbecause they are the cheapest, or the only materialavailable. A number of these are as follows, the approximateratios of the maximum use of some of the most impor-. Often a good deal more hand labor is used in the erection of wooden poles than is really economical portant communication circuits. Its short life, greatweight and high cost makes it one of the less desirablepole woods. Although the total number of white oakpoles reported in 1915 did not materially differ fromthose of previous years, there was a very peculiarchange-about. The communication companies, which upto that time had used about 90 per cent of the annualcut, leaving about 1 per cent for power, light and rail-ways and about 9 per cent for the steam roads, in thatyear took but 19* per cent, while the steam roads took73 per cent and the electric companies 74 per cent. Red oak has all the shortcomings of white oak, and inaddition some of its own. Its use is so limited that ithardly deserves mention. It is used almost entirely onlight short-pole communication circuits of minor im-portance. It furnished but per cent of the totalcut of 1915. Cypress S
