By^ far the most common position for the gallery is m some 

 angle of the web, [see example X]. It is usually located in that 

 angle which contains a crack or a hole or some foreign body 

 within which or under which the gallery can be concealed. But 

 this is not always the case. I have often seen the gallery in a 

 corner which contained no contrivance which might be utilized 

 as a shield for the web, when, at the same time, another corner 

 of the web afforded ample facilities for such concealment. 



When the web is inclined, the gallery is sometimes in the 

 lowest portion of the web, as in example VI and sometimes 

 in the highest portion of the web, as in the following example. 



Example XX. — Location : window-sill. Main sheet is in- 

 clined, highest at one place upon the wall, from which it slopes 

 in three directions to the sill. Gallery at the highest point. To 

 prevent the roof of the gallery from collapsing, tension lines ex- 

 tend from the top of the gallery, over the m^in sheet, to the 

 sill. Guard web absent. Snares absent. 



Although the gallery is usually situated in an angle, it is 

 not always thus located. It is often appended to one of the 

 sides of the web. Example III is an illustration. There the 

 galleries situated half way between the two extremes of its web. 

 In the shadow, half way between the two extremities of 

 that treacherous bridge, the spider awaits its victim. Could 

 man have selected for it a better station ? I will cite one other 

 example. 



Example XXI. — Location: angle between a stone wall 

 and a wooden post. Main sheet triangular, attached in the 

 angle between the wall and post. Gallery in a hole in the wall 

 at about one third of the length of the web from the intersection 

 of the wall with the post. It is a noteworthy fact that in this 

 case there was a crack in the corner in which the gallery could 

 have been constructed. Guard web quite high, highest near the 

 wooden post. Snares very scarce 



The following example is a more striking illustration of the 

 same thing. 



Example XXII. — Location: angle between stone wall and 

 wooden post. Main sheet triangular, horizontal, attached in 

 the angle between the wall and the post. Gallery on the 

 wooden post at cpiite a distance from the intersection of the
