ticated milk yields, the only milk yields to be recognized being the official milk records of the Scottish Milk Records Association.

FUTURE DEVELOPMENT.

a

In a general sense progressive dairy farmers may be divided into two groups:

(1) Those desiring official authenticated records above suspicion, in the first instance to enable them to improve the milking qualities of their herds, but with the further object of establishing the reputation and enhancing the selling value of their stock. These are willing to go to considerable expense and trouble to obtain such records.

(2) Those requiring only private records to enable them to eliminate the poor-milking cows and increase the number of good-milking cows, with a view to the more economical production of milk. The latter prefer a milk record at the minimum of inconvenience and expense. Many of them have only small herds. Many also feel that their cows are not sufficiently good milkers to be included in a scheme of official records.

The association considers that the requirements of both groups could probably be more fully met by a separate system of recording for the owners of unregistered herds who can not see their way to adopt the official system, and are introducing a scheme of private or unofficial milk records whereby the dairy farmer may become his own recorder. It is hoped to bring this new scheme into operation in Scotland in 1924, and that it will establish milk recording on a wider and more popular basis, and ultimately induce a greater number to adopt the official system.

The new scheme is a very simple one. There will be no recorder to accommodate and no form of inspection. The scheme is to apply only to cows and heifers which are not registered by a recognized breed society and to the herds of owners who have not been members of a local milk recording society within a period of five years previous to application. The owner or his agent is to weigh the milk of each cow, evening and next morning, at least once every 21 to 28 days, and to enter the results in a special byre sheet provided by the association. The byre sheet is to be immediately posted to the association's offices to be calculated and extended there. and returned to the owner of the herd. A special private or unofficial record book for each herd will be written out in the association's offices. At the end of each recording season the results will be summarized, and the record books and copies of the summary sheets will be sent to the respective owners of the herds. Each member will be given the use, free of charge, except for upkeep, of a special spring balance and pail, and will be required to pay only a small annual subscription of sixpence per cow toward the clerical work.

The ideal before the association is to have every dairy herd in Scotland included in one or other of the association's two schemes of milk recording.

TASK OF THE GOVERNMENT DAIRY EXPERTS WITH REGARD TO

MATTERS OF DAIRYING. A. J. SWAVING, Ph. D., inspector of dairying, chief of dairy division of the gen

eral direction of agriculture, Ministry of Home Affairs and of Agriculture, The Hague.

In the Netherlands there are at present ten Government dairy experts and one assistant Government dairy expert with a staff of four head assistants and six assistants. In each Province there is one Government dairy expert or assistant Government dairy expert, however, with the proviso that two Government dairy experts are appointed in the Province of South Holland, whereas in Friesland the organizations interested have a short time ago supplied the want of enlightenment by means of their own staff.

The expert's task comprises: To enlighten associations or private persons at farms and dairy factories concerning butter and cheese making and sometimes concerning cattle breeding; to give instruction at several agricultural winter colleges, at courses for the education of agricultural teachers, at courses in agricultural instructions as well as at a very great number of courses in milk examination, theoretical and practical butter and cheese making, and courses for the education of assistant managers, headmasters of dairy factories, milk controllers, butter and cheese makers; to hold lectures, which are accessible to everyone, free of charge; to give assistance to the preparation and execution of measures or of experiments of general importance (barn competitions, grading of butter and cheese, milking competitions, etc.); to make simple tests concerning dairy products to trace defects of butter and cheese.

Though also at other places, the dairy experts in the Provinces of Utrecht and North Holland and in the eastern part of the Province of South Holland in particular are occupied in giving theoretical and practical instruction in order to improve cheese making and eliminate cheese defects and other working troubles. The instruction of these experts is besides of great use when cheese makers meet with difficulties as to the observance of the regulations of cheese control stations.

The care for the improvement of milk production is considered by the Government dairy experts everywhere most diligently, and they supervise at the same time the work of the breeding and cow testing associations with respect to milk control (milk lists).

In conclusion it may be mentioned that in the interest of mutual contact as well as to remain in touch with the Government one or two meetings are held annually by the dairy experts under the direction of the inspector of dairying of the direction of agriculture.

On these occasions different subjects concerning the work and the sphere of activity of the dairy experts are discussed and questions concerning matters of dairying and cattle breeding are looked into.

DAIRY INSTRUCTION GIVEN BY THE COOPERATIVE DAIRY

ORGANIZATIONS IN THE NETHERLANDS. J. A. GELUK, secretary of the General Netherlands Dairy Union, The Hague.

A rather important part of the instruction of the lower staffs of dairy factories in Holland is given by the provincial organizations of cooperative dairy factories and the federation which combines these provincial organizations (eight in number), the General Netherlands Dairy Union.

According to the report in another paper relating to the work of the Government dairy experts, the task of these officials also comprises teaching assistant managers of dairy factories, milk controllers, butter makers, cheese makers, and separator attendants to prepare them for their tasks. The courses of the provisional dairy organizations are held partly in connection with these and partly independent. In so far as the provincial dairy organizations have technical and administrative staffs of their own, which is the case with seven of them, the courses for the lower staffs of the affiliated factories are given by their own functionaries. The lessons in the subjects for which there are no teachers are then, as a rule, given by the Government dairy expert in the Province concerned.

For the education of engineers, courses are also organized by all the provincial organizations of cooperative dairy factories. The lessons are given on the part of the General Netherlands Dairy Union by a teacher-engineer, whose task comprises also advising affiliated factories about engine-room and boiler-house problems.

As a rule, these courses are supervised, as far as the provincial associations are concerned, by a committee appointed for the purpose by the dairy organizations.

In 1908 examinations were instituted by the General Netherlands Dairy Union for the obtainment of certificates for the above-mentioned functions in a dairy factory. Though the courses mentioned are not directly connected with these examinations, that is, following a course is not required for admission to the examinations, it is a fact that the requirements of the examination are dealt with.
