skill of the tuber fails to peel off when rubbed. The produce per I'dti. 

 also varies from about 35 tons being greater in Summer than in Win- 

 ter. However, the price per ton is lower in the former than in the 

 latter case. 



VII : Potato is one of the most cultivated plants. It is of great 

 importance as affording food both for human being and for stock ; next 

 to the principal cereals it is the most valuable of all plants for human 

 food. It is also used -for various purposes in the arts. For human use 

 it is variously prepared. For stock potatoes arc used both raw and 

 boiled. The tuber in a fresh state contains about 71 80 / of water 

 and 12 27 / of starch. There are considerable differences, however, 

 in different varieties, in different stages of maturity and in different 

 soils and seasons. 



Its starch is easily separated and is cheaper than any other kind. 

 It is largely used in textile manufactories, and in preparing a coarse 

 spirit known as Potato brandy, etc. etc. 



VIII : Potato requires care in cultivation. A light friable sandy loam 

 is necessary, plenty of well-rotten dung and much capillary moisture. 

 Deep and thorough tillage, frequent surface stirring and careful 

 weeding. 



It is very tender to frost and requires great attention. 



As regards manuring this is one of the main points in Potato cul- 

 ture. Baladi manure is used the amount varying from .10 15 cb.m. 

 per i'edn. and depending on many circumstances. (Jreat care is requi- 

 red in watering the crop and the praclicc of applying water to the 

 plant just before harvesting, the object beting apparently to cause 

 the tubers to swell and consequently to increase in weight, must be 

 avoided. 



Spinacea oleracea : Sabanekh : Spinach ; Chenopodiaceae 



1 : (a) Roumi, Round or lettuce-leaved Spinach ; (b) Baladi or 

 prickly-Spinach. 



The former is less popular-- It is of a low and spreading nature, 

 with leaves broad more round and blunt, soft and flabby and the seed 

 or I'm it more or less round and smooth. This is the S. Glabra of some 

 Botanists. 



The latter is extensively grown. It is more or less erect, with lea-
