146 CnEMICO-AGRICULTURAL TOUR. 



College ; and I was informed, that this mode of manuring was 

 found to be attended with the best results. 



There is an "Economic Garden" attached to this institution, 

 which, though it is little more than an acre in extent, has nearly a 

 thousand different plants growing there, and those are selected 

 which are most likely to interest the agriculturist. This garden is 

 divided into small squares, one of which is devoted to each kind of 

 plant or vegetable under cultivation : and in order to facilitate the 

 reference to any particular one, there is a map of the garden, where 

 each of the squares are indicated and numbered, in accordance 

 with the figures attached to the squares in the garden ; so that, 

 by referring to this map, with its accompanying catalogue, the 

 place where any plant grows in the garden may be quickly discov- 

 ered. 



A series of experiments are also carried on with great care, and 

 the plants under experiment are placed in small squares which are 



•surrounded by well-tarred boards, forming, in fact, a kind of box, 



-of about 6 feet in length by 4 in breadth, and about 4| feet in 

 depth. In these are placed different soils, composts and mineral 

 manures — the object of such experiments being to test the correct- 

 ness of some of Liebig's doctrines respecting mineral and other 



►manures. 



The chief object of this institution is to give a sound and practical 

 ■agricultuffd education to young men who purpose becoming land- 

 stewards or farm-bailiflTs ; but, in addition to this, it has, as a subor- 

 dinate object, ihc instruction of lawyers and gentlemen in all matters 

 relating to landed property. This instruction is communicated by 

 means of lectures, and by witnessing and taking part in the practi- 

 cal operations of the field and stall. The indoor course of study 

 seems to be most comprehensive, and appeared to me to embrace 



• every species of knowledge likely to be of practical use to the 

 agriculturist. The course of instruction is divided into four terms 



•which occupy about two years, The pup"ls do not either board or 

 reside in the college, but lodge in the town, where they can obtain 



•apartments very cheaply. 



I visited also the Botanic Garden at Bonn, which is situated 

 close to the Agricultural College, and commands a fine view of the 

 Drachenfelti and the adjacent hills of this very beautiful portion of 

 the Rhine. The garden is small, but possesses a good general col- 

 lection of plants; and I observed there a great variety' of grasses,
