PRACTICAL BOOK OF GARDEN ARCHITECTURE 



ing built about eight feet apart and eight feet high 

 the finish of the roof will determine whether the 

 structure is to be of rustic design, or expressive of 

 simplicity and dignity. When built amid rustic sur- 

 roundings, the surfa.ee of the posts may be left in the 

 rough, and bark-covered beams and rustic saplings 

 may form the roof. For the home and garden of 

 stately type, the posts should be smooth-finished, the 

 overhead cross pieces being planed lumber and the 

 heavy rafters overhanging each side of the pergola 

 from one to two feet, with their ends carved in true 

 pergola fashion. 



There is no regular rule for cutting the rafter and 

 girder ends. Neither do the pergolas of classic de- 

 sign, built in harmony with a country seat mansion, 

 adhere to any set rule of classic construction. It is 

 true that experienced architects will talk learnedly 

 of Greek Doric columns, that should be built to a 

 height of seven times the bottom diameter of the 

 shaft ; and be equally precise in regard to the Tuscan 

 and the Roman Doric as regards their height and 

 their capitals. But hard and fast rules of classic 

 porticoes and loggias need not be applied to pergolas 

 and arbors. Good taste and good sense should be 

 exercised to keep the structure in harmony with the 

 house and its surroundings and the result will be 

 pleasing.
