The effect of absence from food of Vitamin A is retarded growth 

 ending in death, eye disease in some cases, and often onset 

 of rickets. 



The absence of Vitamin B leads to retarded growth ending in 

 death, and in poultry, the disease known as " leg weakness." 



The absence of Vitamin C leads to the onset of scurvy. 



Several inquirers have asked for information as to the best 

 sources from which to obtain these vitamins. Vitamin A is 

 present in fish liver oils, green plants (including lucerne, clover, 

 cabbage and hay), milk, egg yolk, animal fats, and some roots 

 such as carrots, parsnips and mangolds. Vitamin B is present 

 in seeds and grains, generally distributed in the germ and out- 

 side layers. It is also present in yeast, milk, egg yolk, green 

 plants, carrots, potatoes, turnips, mangolds and beet. Vita- 

 min C is present in green vegetables, particularly cabbage and 

 its allied species. It is also present in orange and lemon juice, 

 germinated seeds, swedes, turnips, potatoes, tomatoes and milk. 



The aim of the farmer should therefore be to arrange his 

 ration so that the diet contains sufficient of the three vitamins. 

 With the table given this should prove an easy matter. 



One of the most Important features of the Ministry's scheme 



for instruction in practical horticulture is the establishment by

enable growers to see the trials of varieties best suited to local 

 conditions and of up-to-date methods of culture and manuring. 



In the Holland Division of Lincolnshire the production of 

 potatoes, peas, celery, green vegetables, fruit and flowers has for 

 many years been a most important industry. The need for 

 assisting growers with horticultural advice in the conduct of 

 their industry has led to the establishment at Kirton, near 

 Boston, of a Horticultural Station covering an area of 100 acres. 

 This year there are being carried out trials of potatoes, peas, 

 spring cabbage and cauliflowers, and a start has been made with 

 fruit plots and trials of narcissi, daffodils and tulips. 



Seventy per cent, of the area is devoted to vegetable trials, and 

 of these perhaps the most important are those of spring i-ahhagc '
