The pens are stubs of various widths, cut off obliquely, and when inuse should not, as ordinarily, be dipped into the ink, butthe latter should be inserted, by means of another pen,between the top of the Soennecken pen and the brassfeeder that is usually slipped over it to regulate the flow.The Soennecken Round Writing Pens are also by farthe best for lettering in Old English, German Text andkindred types.The improvement due to the addition of a few straight lines to an ordinary title will become evident by comparing Figs. 153 and 154. The judicioxis ~ use of word ornaments, such as those of alphabets 33, 42, 49, and of several of the other forms illustrated, will greatly enhance the appearance of a title with-out materially increasing the time expended on it.

On page 95 a large number of corner designs and borders is presented, one-third of them orig-inal designs, by the writer, for this work. The principle of their construction is illustrated by Fig.155, in which the larger design shows the necessary preliminary lines, and the smaller the completecorner. It is evident in this, as in all cases of interlaced designs, that we must first lay off eachway from the corner as many equal distances as there are bands and spaces, and lightly make anetwork of squares — or of rhombi, if the angles are acute—by pencilled construction-lines throughthe points of division. 267. Shade lines on borders. The usual rule as to shade lines applies equally to these designs,thus: Following any band or pair of lines making the turns
