The earliest windows were filled with small diamond shaped panes leaded into the casements and the casement window was universally used. In the fore part of the eighteenth century, double or single hung sash windows became the fashion and were very generally substituted for the older casements by alterations made in the manner alluded to in Chapter III, although, quite frequently, particularly in the Middle and Southern Colonies, no change in the shape or dimensions of the window openings was considered desirable or necessary. The lights for the sashes were universally small and it was not until the end of the eighteenth century that they increased appreciably in size. It should be remembered that a great deal of the charm and individuality of fenestration during both the early Colonial and Georgian periods was due to the manifold divisions of the lights--with lead in the first instance and with heavy muntins in the second. A good many of the old leaded casements that had endured, despite the favour of the new styles, till the outbreak of the Revolutionary War disappeared at that time, the lead being melted to make bullets. This is said to have been the fate of the original windows in the Church of St. David at Radnor. Paint, in the first years of colonisation during the seventeenth century, though not unknown, was not in common use and it must be admitted that the old woodwork, whether oak or pine, took on a delightful tone in the course of a few years from the combined agency of the atmosphere and the smoke of wood fires. In Pennsylvania and the neighbourhood, paint both inside and out seems to have been used from the first. It should be remembered, particularly in this connexion, that paint for either exterior or interior use in the Colonial and Georgian periods was not invariably white. Colours were frequently used and specific reference has been made in Chapter VIII to the employment of paint of various colours for panelling and other interior woodwork.
