very much, viz.: the crossing of European grape vines with 

 American, producing a hybrid that is much less subject to the 

 attacks of the phylloxera. The illustrations of soil formation 

 and production of turf, etc., etc., were most interesting. We 

 were shown a collection of rocks, minerals, sand, soil, etc.,, 

 forming a wall about twenty feet square in which not only are 

 the different strata shown, but in the exact proportions as they 

 are found in the earth's crust in the neighbourhood. This was- 

 a presentation by a number of former students as a mark of 

 esteem to Professor Kuhn. Practical agriculture for profit 

 is conducted on a farm three miles from Halle. We were 

 next conducted through the Veterinary department. The 

 hospital accommodation is excellent and the clinique is ample 

 for teaching agricultural students comparative medicine. 



The Zoological department is a wonderful establishment 

 which must have cost enormous sums of money to procure, 

 and a large sum annually to maintain. It contains specimens 

 of all breeds of horses and asses, with the result of crossing in 

 every degree. It also contains nearly all kinds of cattle : 

 Shorthorns, Polled Angus, Devons, Ayreshires, Kerry, etc., 

 as wel.1 as numerous native breeds, wild breeds, Yaks, Buffalo, 

 etc., and the crosses resulting from mating experimentally. 

 Sterility is almost the rule in hybrid males, while the female 

 will often breed. In twins the male is usually sterile, but the 

 female breeds. 



Pigs. This class is very numerous, embracing specimens of 

 every known wild pig, and every domestic breed. 



Sheep. Sheep of every known breed are there, including the 

 fat tails and big horns (Rocky Mountain sheep), lop eared, etc., 

 etc. There are also goats in great variety and the results of 

 crossing them with sheep. 



Poultry. There are poultry of every kind, swans, geese, 

 ducks, wild and domestic fowls of various breeds ; pigeons, 

 pheasants, and experimental crosses of these. 



We were shown the record book of the breeding operations, 



which is very complete as to dates and results.
