iiiatinity and conduce to a liard berry with a high protein (gluten) content. On the 

 othcT hand when the vegetative period is lengthened and ripening deferred, as by cool 

 ami damp weatlier, the tendency will be towards the production of a soft and starchy 

 j:rain. 



Fodders and Feidlnfj Stuffs. — This chapter deals witli the analysis and nutritive 

 value of a number of forage plants and concentrated feeding stuffs. These include 

 by-products of the distillery, brewery, starch factory, and linseed oil mill. Several 

 molasses feeds are also reported on. 



We have during the year analysed a large series of samples of elevator screenings 

 and of weed seeds separated therefrom, to determine their food value. The publica- 

 tion of these data, however, is deferred for the present, pending the completion of our 

 inquiry as to the practical usefulness of these screenings in stock feeding. 



Fertilizer Experiments with Potatoes. — Information is furnished on the profitable 

 use of fertilizers on the potato crop, as gathered from experimental work carried on 

 at the Experimental Station at Kentville, N.S., and at the Experimental Station, 

 Frederictoui, N.B. In this investigation the usual forms of nitrogen, phosphoric acid 

 and potash found in the fertilizer market were used, and the tables of data given 

 show the profits obtained from the various mixtures employed. The largest profits 

 followed in the majority of instances the application of mixtures containing all three 

 elements of plant food, and a further consideration of the data clearly shows that 

 moderate, rather than very large, dressings were the more profitable. 



The Relative Value of Field Roots. — This is a continuation of an investigation 

 that has been carried on for isome years. The series includes mangels, turnips a»d 

 carrots, the analysis being made from roots grown on the Central Farm, Ottawa. 



The influence of heredity in mangels has been further studied, using the Gate 

 Post and Giant Yellow Globe. The former variety has for the past fourteen years, 

 during which the subject has been under investigation, proved invariably the better 

 root, both as to dry matter and sugar. 



Sugar Beets. — Three of the leading? varieties of sugar beets, Vilmorin's Improved 

 A., Vilmorin's Improved B., and elein Wenzleben, have been grown at fourteen of the 

 Dominion Experimental Farms and Stations and representative roots therefrom have 

 been submitted to analysis. The data, as a whole, are very satisfactory, indicating 

 that beets rich in sugar and eminently suitable for factory purpose.?, may be grown in 

 widely distant parts of the Dominion. 



Naturally-occ^irring Fertilizers. — This chapter includes the analysis of marls, 

 limestones, and other materials of fertilizing value sent in during the year. It also 

 furnishes information as to the use of lime and its compounds in practical agri- 

 culture. 



Insecticides and Fungicides. — A series of thirteen samples of arsenate of lead, 

 representing the more important brands on the market, has been examined. The 

 detailed analyses are given in tabular form and notes added as to the more salient 

 properties of this valuable insecticide. 



Several insecticides and sprays recently put upon the market, have also been 

 analyzed and are here reported on as to their probable value. 



Fertilizing Value of Rain and Snow. — The data for the seventh year of this investi- 

 gation are here presented. During the past year there were furnished from these 

 sources for the enrichment of the soil, 6,208 pounds of available nitrogen per 

 acre. The average amount, per annum, for the past seven years, is 6-182 pounds 

 per acre. 



Meat Inspection Division. — This work consists in the analysis of samples col- 

 lected by the Inspectors of the Meat Inspection Division, Health of Animals Branch
