such alterations as might seem desirable, for wider 

 circulation, especially among those connected with 

 Agricultural Investigation, or Agricultural Education,

 Accordingly, some changes in form and arrangement 

 have been made, and the record has been brought up 

 to date, for the purposes of the present issue. With 

 the exception of such changes, the report is essentially 

 the same as that presented, in 1889, to "The Lawes

 each Series numbered in chronological order. They also

 those given in the "Memoranda " (see below), and they 

 are given here, not only for purposes of general refer-

 of the papers, or to the papers themselves, which are 

 referred to in the Eeport under the same numbers as 

 those in the lists.

 of the Field and other experiments conducted on the Farm

In this annual Memorandum, there is first given a 

 general description of the lines of enquiry in progress,

 reference to where they appeared, and then are given 

 summaries, chiefly in the Tabular form, and for the
