attached to the body portion of the terra-cotta pipe, shown in 
Fig. 4,T, by means of the notch formed by the clay flap in en- 
veloping the clay reed, Fig. 11, E (Plate xvi). A good illustra- 
tion of this can be made by attaching a metal mouth-piece to one 
of our modern fifes, Fig. 9 (Plate xvi), and then sawing it asunder 
between the sound-hole, F ig. 9, W, and the finger perforations, 
Fig. 9, Y, Y (shown by the dotted lines). This having been done 
the result would be an instrument similar to F igs. I and 4 (Plate 
xvi). i 
A pitch-pipe, showing an advance in construction upon that 
already described, resembling somewhat a retort in form, is shown 
in Figs, 1-3 (Plate xvir). It is modeled in four pieces, and the 
clay reed has been made in the same manner as those upon the 
Sections shown in Figs, 1oand 11 (Plate xv1), differing only in the 
form of the body, which is circular. In order to accomplish the 
modeling of the body portion, it would be necessary to use a cir- 
cular form, dividing it into two portions, Fig. 2 (Plate xvit), one 
half being modeled on one portion, Figs. 2, R (Plate xvi), and 
the other half upon the other side, Figs. 2, S (Plate xv). The 
two halves being made so as to correspond nicely when joined 
together. The double pitch-pipe, shown in Fig. 4 (Plate xvm) 
demonstrates that this method was pursued, from the fact that 
while in the kiln the two halves which compose the body have 
been Separated by the action of the heat, thus showing its con- 
struction, By careful examination traces of this jointure can 
im site Some of the pitch-pipes, although in most cases it is 
Hating to detect it, so nicely have the marks of jointure been 
tea by skillful modelings. Each one of the retort-shaped 
ments, Figs, 1-3 (Plate xvi) is pierced by a stop-hole,® Fig. 
Fash iy xvu), which is placed to the left hand side of a line 
the a Pre ly around the body of the pipe, passing through
