But we are quite sure that hedge-row timber is almost useless in itself, and a pest to all who must live under it. Hedges themselves are usually too many, and these too thick through them; and when it comes to be understood that the enclosures are smaller, the hedges often greater, and hedge-row timber thicker on good than on bad lands, some idea may be formed of the mischief which is inflicted by thus hemming in fine land from light and air. The following tables, by Mr. J. Bravender, land-surveyor, of Cirencester, are the results of an “examination of the fields contained in 120 parishes:”— TABLE OF ADMEASUREMENT OF FENCES. +---------------+--------+--------+---------+--------+---------+--------+ | |Average | | Length | |Quantity |Quantity| |Geological |quantity| Length | of | Width |occupied | per | |Formation, &c. | of | of |fencing, | of |by fences|hundred | | | each |fencing.|per acre.|fencing.|per acre.| acres. | | | field. | | | | [24] | | +---------------+--------+--------+---------+--------+---------+--------+ | | Acres. | Chains.| Chains. | Links. |Perches. | Acres. | | 1.
