Survey and Surveyor. A " survey " is an attentive view, a look, 

 or a careful examination of an object, usually made in con- 

 nection with fixing or assessing its value. A " surveyor " is 

 a qualified and experienced person, who views and examines 

 for the purpose of ascertaining the condition, quality or 

 quantity. This work, and the expert asso'ciated with it, 

 form an important detail in the timber and wood trades 

 touching the forest growth, the felled trees, the floating 

 rafts, the mill-stocks, and the converted goods through 

 their every phase ; wood being a damageable class of goods, 

 and a prey to fire, Surveyors, Lloyds-marine, and others, 

 are established at most ports and centres of trade. 



Swage. A tool used to spread the points of teeth of a band or 

 circular saw.

Sweet (or Spanish) Chestnut (Castanea vesca). Introduced into 

 Britain by the Romans. A hard durable wood, much 

 resembling oak. but can be distinguished from it by the eye 

 not detecting the medullary rays. The wood is more diu-able 

 young than old and diminishes in value after reaching the 

 age of sixty, though it may live for centuries. Used by 

 cabinet makers, undertakers and turners, and when young 

 as a substitute for oak. Its failing is ring or heartshake 

 when approaching maturity. 



Sweet-woods. Embrace trees that produce edible fruits ; they 

 are mostly hardwoods inclined in colour to brown and even 

 darker shades. They rank as perishable woods from being 

 prone to the attack of the worm, or larvce of the furniture- 

 beetle, after the wood is seasoned and placed in work. 

 ' Walnut " and " pear-tree wood " may be taken as exam- 

 ples ; exceptions, with regard to the fruit, are offered by 

 the ash and the lime, but the sweetness of the latter is 

 noticeable in the odour of its blossom.
