grained and spreading. The chaff is uniform in colour, not too firmly- 

 attached, and holds the grain only fairly well, deep, 

 close-lying, long, acutish, short-awned towards tip 

 of the ear, stiff, and has a dull appearance. The ik ^ 



grain is amber-coloured or reddish, quite small, ™ 



straight, opaque, rather flat-bosomed, and blunt at 

 both ends; it has an abundant brush. A back-crease 

 is barely visible ; when cut across with a knife the 

 section usually appears horny. 



Fultz is a well-known latish variety, somewhat 

 above medium height. The best strains of it are pro- 

 lific, and yield a grain considered in America to be of 

 very good milling quality. It is highly resistant to rust. 

 Manitoba and Russian resemble this variety in type. 



Prominent characteristics. — Eather tall, strong, 

 whitish-yellow straw, bald yellow heads, grain of 

 medium size, considered in America to be of very good 

 milling quality, somewhat late, prolific, not liable to 

 shell, highly resistant to rust. 



While on this subject it may not be amiss to ex- 

 tract from my letters a few notes on the experiment Fig. 7.— Bar of Fuitz, one- 

 wheat plots at the Wagga Experiment Parm and the ^^ll^ *"^^ '^''- ^^'^^"^ ^"" 

 Bathurst Experiment Farm. As explained in a 



recent number of this journal* these experiments are carried out partly on 

 the row system, and the nature of the system is shown admirably in some 

 recently taken photographs which are here inserted. (Figs. 11, 12, and 19 

 on the following pages.)

Fig, 11 is of a typical plot, designed to show the difference in yield from 

 seeds of various sizes. The left-hand stocks are from large need, the next 

 from medium sized seed, the next from small seed. These are from a series 

 of several hundred experiments extending over three years. The results 

 will be published in a few months, and will be far more interesting and useful 

 than those of any other experiments hitherto conducted at Wagga with wheat. 

 Fig. 12 shows some of the manure experiments. Various manures are used 

 in the double rank-growing drills. The intervening three are without manure. 

 These are from a series of over 200 experiments. This is the third year. 

 The results will be ready for publication next year. 



There are so many inquiries for a rust-proof wheat and for a "pickle" 

 that will cure rust that I take this occasion to repeat that there is no such 

 thing known as a wheat that is proof against rust. Some varieties resist 

 rust to a considerable degree, and a few in a marked degree, but none of 

 them are proof against the disease.
