The side, which was used for the scraping process, is provided with seven parallel 
straight grooves, each ridge of which is also provided with another shallow groove.

thickness 2.8 cm. ound 1.35 m. below the surface. 
This form has, as far as I have been able to ascertain, never been found on the 
Atlantic coast of Costa Rica, or in the highlands, but only in Nicoya. Similar 
bark-scrapers, but of nearly rectangular shape, I found in the 
year 1898 in various places on the Pacific coast of Salvador, in 
the present territory of the Pipiles. In Guatemala, in the city 
of Escuintla on the Pacific slope, I observed an ancient tool of 
the same general shape as the Costa Rican barkscraper, but 
entirely flat and smooth on both sides. It was of large size, prob- 
ably weighing about two kilograms. It had been found years 
ago while making excavations for the foundations of a house. It 
was now used by the owner of a small hotel (Anderson’s) for 
keeping the door open. The owner refused to part with it.
