152 MASSACHUSETTS AGRICULTURE. 



I have not tried to see how much corn I could raise, but have 

 taken about an average of our Plymouth County soils and 

 applied the amount of manure which I should think would be 

 economical for general cultivation, kept the ground well stirred 

 and free from weeds, and the result has been as above. It will 

 be seen that Plot No. 2, where the manure was ploughed in four 

 inches, on land previously ploughed seven inches, produced 

 about three per cent, more than where it was harrowed in, about 

 twelve per cent, more than where it was ploughed in deep, 

 about eighteen per cent, more than where the manure was left 

 upon the surface, and about seventy-three per cent, more than 

 the plot without any manure. The season has proved moist, 

 which would appear to be favorable to the plots where the 

 manure was near the surface.

Statement of G. Sf G Graft. 



Tlie following statement is furnished respecting such varie- 

 ties of evergreen trees and shrubs as have been cultivated and 

 tested by us. The land upon which most of the trees grow, 

 lies rather low and level ; the soil is a strong, black loam, not 

 very deep, with a yellow subsoil, resting on hard-pan gravel, 

 about eighteen inches from the surface. We never apply 

 manure to evergreens. The newer kinds are sheltered some- 

 what, by standing in the nursery, among larger trees, both 

 deciduous and evergreen. Some of the kinds — especially those 

 that are very common and well known — will be passed over 

 without remark ; such as the white and pitch pines, balsam fir, 

 white or swamp cedar, and the saviti or red cedar ; and where 

 nothing is stated to the contrary with regard to any variety, 

 it may generally be considered as perfectly hardy. This class 

 embraces such trees as the Scotch Pine, Pinus sylvestris ;
