" Sea water might be carried 

 from the sea some distance on the 

 land, to advantage, in the following 

 manner: — Take a one horse cart, 

 and suspend a tight box, rightly 

 shaped, under the axletree ; the 

 box having a valve in the under- 

 side ; drive the cart into the water, 

 and the valve opens, and lets that 

 fluid inio the box; and, when the 

 cart is driven out, the valve closes 

 and holds the water. 



" When the cart is driven out to 

 the ground on which the water is 

 to be spread, this operation may 

 be performed in the manner we 

 shall next describe : A tube is to 

 be provided, say, twelve feet in 

 length, with small holes bored into 

 it at the distance of six inches apart, 

 and the ends of the tube closed; 

 attach this to the under side of the 

 box, crosswavs, at either end, so as 

 to be out of ihe way of the wheels 

 of the cart. 



" When you come to where the 

 water is to be spread, it is to be Kt 

 out of the box into the tube, by an 

 aperture for the purpose; and as 

 the cart moves along, the water runs 

 out of each of the small holes in the 

 tube, and thus sprinkles over a 

 piece of ground of twelve feet wide, 

 till the whole is exhausted. 



" With the next load ; begin 

 where the water ceased runiiinji 

 before, and thus continue the wa- 

 tered strip across the (ield. Then 

 take another strip of twelve feet 

 wide, adjoining that already water- 

 ed, aixi thus proceed till the wliole 

 has been gone over. 



" In this way a man would carry 

 out. say, forty cart load* a day. at 

 the distance of half a mile, or iialf 

 1R 



that number if a mile; as but little 

 time need be spent, either in load- 

 ing or unloading. About ten loads 

 of a hundred gallons each would 

 probably be suffiiient for an acre 

 at any one time." — Farmer^s As'

SEEDS of Vegetables, "their 

 last product, by which their species 

 are propagated ; being frequently 

 all the fruit of a plant, but some- 

 times only a part nicluded in the 

 fruit. 



" Every seed contains a plant in 

 embr}o. The erribrto, which is 

 the whole future plant in minia- 

 ture, is called the germ or bud ; 

 and is rooted in the cotyledon, or 

 placenta, which makes its involu- 

 crum, or cover. The cotyledon 

 is always double ; and in the mid- 

 dle, or connrion centre of the two, 

 is a point or speck, viz. the em- 

 bryo plantule, which being acted 

 on by the warmth of the sun and 

 of the earth, begins to protrude its 

 radicle, or root, downwards, and 

 soon after, its plumula, or bud, up- 

 wards ; and as the requi-ite heat 

 continues, it draws nourishment by 

 the root, and so continues to unfold 

 itself and grow. 



'^ The two cotyledons of a seed, 

 are a case to the little embryo 

 plant ; covering it up, and shelter- 

 ing it from injuries, and feeding it 

 from its own pioper substance ; 

 which the plantule receives and 

 draws to itself by an infinite num- 

 ber of little filaments, which it 

 sends into the body of the placen- 

 ta. 



" The cotyledons for the most 

 part abound with a balsam dispo3= 

 ed in proper cells : and this seems
