months, from November to March, to the old castle of the Counts 

 Guidi at Paterno near the base of the mountain, and only twelve 

 hundred feet above the sea. During the remaining eight 

 months the head-quarters are at the high elevation of Yallom- 

 brosa. The contrast in the elevations of the two locations 

 favors the maintenance of two distinct arboretums, the one at 

 Paterno showing the vegetation of Southern Italy, and even 

 the tender exotics of the tropics, while on the heights of Yallom- 

 brosa are planted the trees of Northern Europe and America as 

 well as of the Alps. Great varieties of pines, firs, larch, ash, 

 chestnut, oak, beech are cultivated in the nurseries for planting 

 on the slopes and heights of the Appenines. The Director 

 expressed special interest in the culture of the Fraxinus Ameri- 

 cana — our white ash. The students each have their small 

 nursery lots in which they try their hands in planting and 

 trans-planting various trees, thus uniting theory and practice. 



The Institution has its director and five professors, a library 

 containing nearly 2,500 volumes of forest literature; a well 

 furnished chemical laboratory ; a meteorological observatory, 

 where the indications of the thermometer, barometer, pluviom- 

 eter, anemometer, hygrometer and seismometer are regularly 

 recorded ; instruments for tree-measuring and surveying and 

 various arboricultural instruments, models of timber slides ; 

 timber carts; sections of wood, indigenous and exotic, and ob- 

 jects of natural history relating to forestry. The professors 

 are appointed by the King, on the recommendation of the 

 Minister of Agriculture. The number of pupils admissible is 

 sixty. Besides the common rudiments, candidates for admission 

 must pass an examination in history, natural history, algebra, 

 geometry, physics and chemistry. The students wear the neat 

 uniform of the Institution, which is that of a forest guard, with 

 oak twigs of gold lace on the collar and cap. The discipline is 

 mildly military, the students respond to the call of the trumpet 

 instead of a college bell, cannot leave the precincts without 

 permission, and are liable to confinement for insubordination. 

 The students make frequent and sometimes extensive excur- 

 sions through the national and communal forests, with the 

 Professor of Natural History, to observe and collect specimens ; 

 with the Professor of Mathematics and Surveying, to make plans
