A Plan of an arched Frame, to 

 be made of Cast Iron, useful for 

 bestriding Walks, and for sustain- 

 ing Roses, Georginas, and other 

 Plants to be trained over it. — 

 Explanation. Fig. 115. a a, the 

 uprights, which are \^m. broad 

 by a quarter of an inch thick j 

 b, the cross bars ; e, the form 

 of the cross bars : they are 

 about half an inch thick in the 

 middle, and a quarter of an inch 

 thick at each end ; so that they 

 will average about three eighths 

 of an inch in diameter. - 



Fig. 116. shows that the up- 

 rights may be single; but they 

 will be stronger if constructed 

 as in fig. 115. The frame is 

 cast in three pieces, the two 

 uprights and top ; and as there 

 is a groove on the upper end 

 of each upright to receive one 

 end of the top piece, the frame, 

 when brought from the furnace, 

 will require nothing to be done 

 to it except setting up, that is, 

 putting together, and soldering the base of the uprights into stones.
